 ### Methods
 
 <a name="static-method-from"></a>
 
 #### Int8Array.from( src\[, map\[, thisArg]] )
 
 Creates a new typed array from an array-like `object` or an iterable.
 
 ```javascript
 var arr = Int8Array.from( [ 1, 2 ] );
 // returns <Int8Array>[ 1, 2 ]
 ```
 
 To invoke a function for each `src` value, provide a callback function.
 
 ```javascript
 function mapFcn( v ) {
     return v * 2;
 }
 
 var arr = Int8Array.from( [ 1, 2 ], mapFcn );
 // returns <Int8Array>[ 2, 4 ]
 ```
 
 A callback function is provided two arguments:
 
 -   `value`: source value
 -   `index`: source index
 
 To set the callback execution context, provide a `thisArg`.
 
 ```javascript
 function mapFcn( v ) {
     this.count += 1;
     return v * 2;
 }
 
 var ctx = {
     'count': 0
 };
 
 var arr = Int8Array.from( [ 1, 2 ], mapFcn, ctx );
 // returns <Int8Array>[ 2, 4 ]
 
 var n = ctx.count;
 // returns 2
 ```
 
 <a name="static-method-of"></a>
 
 #### Int8Array.of( element0\[, element1\[, ...elementN]] )
 
 Creates a new typed array from a variable number of arguments.
 
 ```javascript
 var arr = Int8Array.of( 1, 2 );
 // returns <Int8Array>[ 1, 2 ]
 ```
 
 <a name="method-copy-within"></a>
 
 #### Int8Array.prototype.copyWithin( target, start\[, end] )
 
 Copies a sequence of elements within an array starting at `start` and ending at `end` (non-inclusive) to the position starting at `target`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3, 4, 5 ] );
 
 // Copy the last two elements to the first two elements:
 arr.copyWithin( 0, 3 );
 
 var v = arr[ 0 ];
 // returns 4
 
 v = arr[ 1 ];
 // returns 5
 ```
 
 By default, `end` equals the number of array elements (i.e., one more than the last array index). To limit the sequence length, provide an `end` argument.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3, 4, 5 ] );
 
 // Copy the first two elements to the last two elements:
 arr.copyWithin( 3, 0, 2 );
 
 var v = arr[ 3 ];
 // returns 1
 
 v = arr[ 4 ];
 // returns 2
 ```
 
 When a `target`, `start`, and/or `end` index is negative, the respective index is determined relative to the last array element. The following example achieves the same behavior as the previous example:
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3, 4, 5 ] );
 
 // Copy the first two elements to the last two elements:
 arr.copyWithin( -2, -5, -3 );
 
 var v = arr[ 3 ];
 // returns 1
 
 v = arr[ 4 ];
 // returns 2
 ```
 
 <a name="method-entries"></a>
 
 #### Int8Array.prototype.entries()
 
 Returns an iterator for iterating over array key-value pairs.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2 ] );
 
 // Create an iterator:
 var it = arr.entries();
 
 // Iterate over key-value pairs...
 var v = it.next().value;
 // returns [ 0, 1 ]
 
 v = it.next().value;
 // returns [ 1, 2 ]
 
 var bool = it.next().done;
 // returns true
 ```
 
 <a name="method-every"></a>
 
 #### Int8Array.prototype.every( predicate\[, thisArg] )
 
 Tests whether all array elements pass a test implemented by a `predicate` function.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v <= 1 );
 }
 
 var arr = new Int8Array( [ 1, 2 ] );
 
 var bool = arr.every( predicate );
 // returns false
 ```
 
 A `predicate` function is provided three arguments:
 
 -   `value`: array element
 -   `index`: array index
 -   `arr`: array on which the method is invoked
 
 To set the callback execution context, provide a `thisArg`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     this.count += 1;
     return ( v >= 1 );
 }
 
 var ctx = {
     'count': 0
 };
 
 var arr = new Int8Array( [ 1, 2 ] );
 
 var bool = arr.every( predicate, ctx );
 // returns true
 
 var n = ctx.count;
 // returns 2
 ```
 
 <a name="method-fill"></a>
 
 #### Int8Array.prototype.fill( value\[, start\[, end]] )
 
 Fills an array from a `start` index to an `end` index (non-inclusive) with a provided `value`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( 2 );
 
 // Set all array elements to the same value:
 arr.fill( 2 );
 
 var v = arr[ 0 ];
 // returns 2
 
 v = arr[ 1 ];
 // returns 2
 
 // Set all array elements starting from the first index to the same value:
 arr.fill( 3, 1 );
 
 v = arr[ 0 ];
 // returns 2
 
 v = arr[ 1 ];
 // returns 3
 
 // Set all array elements, except the last element, to the same value:
 arr.fill( 4, 0, arr.length-1 );
 
 v = arr[ 0 ];
 // returns 4
 
 v = arr[ 1 ];
 // returns 3
 ```
 
 When a `start` and/or `end` index is negative, the respective index is determined relative to the last array element.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( 2 );
 
 // Set all array elements, except the last element, to the same value:
 arr.fill( 2, -arr.length, -1 );
 
 var v = arr[ 0 ];
 // returns 2
 
 v = arr[ 1 ];
 // returns 0
 ```
 
 <a name="method-filter"></a>
 
 #### Int8Array.prototype.filter( predicate\[, thisArg] )
 
 Creates a new array (of the same data type as the host array) which includes those elements for which a `predicate` function returns a truthy value.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v >= 2 );
 }
 
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.filter( predicate );
 // returns <Int8Array>[ 2, 3 ]
 ```
 
 If a `predicate` function does not return a truthy value for any array element, the method returns an empty array.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v >= 10 );
 }
 
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.filter( predicate );
 // returns <Int8Array>[]
 ```

 };
 
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.filter( predicate, ctx );
 
 var n = ctx.count;
 // returns 3
 ```
 
 <a name="method-find"></a>
 
 #### Int8Array.prototype.find( predicate\[, thisArg] )

 function predicate( v ) {
     return ( v > 2 );
 }
 
 var arr = new Int8Array( [ 1, 2, 3 ] );
 
 var v = arr.find( predicate );
 // returns 3
 ```
 
 If a `predicate` function does not return a truthy value for any array element, the method returns `undefined`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v < 1 );
 }
 
 var arr = new Int8Array( [ 1, 2, 3 ] );

 // returns 2
 ```
 
 If a `predicate` function does not return a truthy value for any array element, the method returns `-1`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v < 1 );
 }

     if ( i < arr.length-1 ) {
         str += ' ';
     }
 }
 
 arr.forEach( fcn );
 
 console.log( str );
 // => '0:1 1:2 2:3'
 ```
 
 The callback is provided three arguments:

 // Reverse the array:
 arr.reverse();
 
 var v = arr[ 0 ];
 // returns 3
 
 v = arr[ 1 ];
 // returns 0
 
 v = arr[ 2 ];
 // returns 2
 ```
 
 <a name="method-set"></a>
 
 #### Int8Array.prototype.set( arr\[, offset] )
 
 Sets array elements.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3 ] );
 // returns <Int8Array>[ 1, 2, 3 ]
 
 // Set the first two array elements:
 arr.set( [ 4, 5 ] );
 
 var v = arr[ 0 ];
 // returns 4
 
 v = arr[ 1 ];
 // returns 5
 ```
 
 By default, the method starts writing values at the first array index. To specify an alternative index, provide an index `offset`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3 ] );
 // returns <Int8Array>[ 1, 2, 3 ]
 
 // Set the last two array elements:
 arr.set( [ 4, 5 ], 1 );
 
 var v = arr[ 1 ];
 // returns 4
 
 v = arr[ 2 ];
 // returns 5
 ```
 
 <a name="method-slice"></a>
 
 #### Int8Array.prototype.slice( \[begin\[, end]] )
 
 Copies array elements to a new array with the same underlying data type as the host array.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.slice();
 
 var bool = ( arr1 === arr2 );
 // returns false
 
 bool = ( arr1.buffer === arr2.buffer );
 // returns false
 
 var v = arr2[ 0 ];
 // returns 1
 
 v = arr2[ 1 ];
 // returns 2
 
 v = arr2[ 2 ];
 // returns 3
 ```
 
 By default, the method copies elements beginning with the first array element. To specify an alternative array index at which to begin copying, provide a `begin` index (inclusive).
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.slice( 1 );
 
 var len = arr2.length;
 // returns 2
 
 var v = arr2[ 0 ];
 // returns 2
 
 v = arr2[ 1 ];
 // returns 3
 ```
 
 By default, the method copies all array elements after `begin`. To specify an alternative array index at which to end copying, provide an `end` index (exclusive).
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.slice( 0, 2 );
 
 var len = arr2.length;
 // returns 2
 
 var v = arr2[ 0 ];
 // returns 1
 
 v = arr2[ 1 ];
 // returns 2
 ```
 
 When a `begin` and/or `end` index is negative, the respective index is determined relative to the last array element.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.slice( -arr1.length, -1 );
 
 var len = arr2.length;
 // returns 2
 
 var v = arr2[ 0 ];
 // returns 1
 
 v = arr2[ 1 ];
 // returns 2
 ```
 
 <a name="method-some"></a>
 
 #### Int8Array.prototype.some( predicate\[, thisArg] )
 
 Tests whether at least one array element passes a test implemented by a `predicate` function.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     return ( v >= 2 );
 }
 
 var arr = new Int8Array( [ 1, 2 ] );
 
 var bool = arr.some( predicate );
 // returns true
 ```
 
 A `predicate` function is provided three arguments:
 
 -   `value`: array element
 -   `index`: array index
 -   `arr`: array on which the method is invoked
 
 To set the callback execution context, provide a `thisArg`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function predicate( v ) {
     this.count += 1;
     return ( v >= 2 );
 }
 
 var ctx = {
     'count': 0
 };
 
 var arr = new Int8Array( [ 1, 1 ] );
 
 var bool = arr.some( predicate, ctx );
 // returns false
 
 var n = ctx.count;
 // returns 2
 ```
 
 <a name="method-sort"></a>
 
 #### Int8Array.prototype.sort( \[compareFunction] )
 
 Sorts an array **in-place** (thus mutating the array on which the method is invoked).
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 2, 3, 0 ] );
 
 // Sort the array (in ascending order):
 arr.sort();
 
 var v = arr[ 0 ];
 // returns 0
 
 v = arr[ 1 ];
 // returns 2
 
 v = arr[ 2 ];
 // returns 3
 ```
 
 By default, the method sorts array elements in ascending order. To impose a custom order, provide a `compareFunction`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 function descending( a, b ) {
     return b - a;
 }
 
 var arr = new Int8Array( [ 2, 3, 0 ] );
 
 // Sort the array (in descending order):
 arr.sort( descending );
 
 var v = arr[ 0 ];
 // returns 3
 
 v = arr[ 1 ];
 // returns 2
 
 v = arr[ 2 ];
 // returns 0
 ```
 
 The comparison function is provided two array elements, `a` and `b`, per invocation, and its return value determines the sort order as follows:
 
 -   If the comparison function returns a value **less** than zero, then the method sorts `a` to an index lower than `b` (i.e., `a` should come **before** `b`).
 -   If the comparison function returns a value **greater** than zero, then the method sorts `a` to an index higher than `b` (i.e., `b` should come **before** `a`).
 -   If the comparison function returns **zero**, then the relative order of `a` and `b` _should_ remain unchanged.
 
 <a name="method-subarray"></a>
 
 #### Int8Array.prototype.subarray( \[begin\[, end]] )
 
 Creates a new typed array view over the same underlying [`ArrayBuffer`][@stdlib/array/buffer] and with the same underlying data type as the host array.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.subarray();
 // returns <Int8Array>[ 1, 2, 3 ]
 
 var bool = ( arr1.buffer === arr2.buffer );
 // returns true
 ```
 
 By default, the method creates a typed array view beginning with the first array element. To specify an alternative array index at which to begin, provide a `begin` index (inclusive).
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.subarray( 1 );
 // returns <Int8Array>[ 2, 3 ]
 
 var bool = ( arr1.buffer === arr2.buffer );
 // returns true
 ```
 
 By default, the method creates a typed array view which includes all array elements after `begin`. To limit the number of array elements after `begin`, provide an `end` index (exclusive).
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.subarray( 0, 2 );
 // returns <Int8Array>[ 1, 2 ]
 
 var bool = ( arr1.buffer === arr2.buffer );
 // returns true
 ```
 
 When a `begin` and/or `end` index is negative, the respective index is determined relative to the last array element.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.subarray( -arr1.length, -1 );
 // returns <Int8Array>[ 1, 2 ]
 
 var bool = ( arr1.buffer === arr2.buffer );
 // returns true
 ```
 
 If the method is unable to resolve indices to a non-empty array subsequence, the method returns an empty typed array.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr1 = new Int8Array( [ 1, 2, 3 ] );
 
 var arr2 = arr1.subarray( 10, -1 );
 // returns <Int8Array>[]
 ```
 
 <a name="method-to-locale-string"></a>
 
 #### Int8Array.prototype.toLocaleString( \[locales\[, options]] )
 
 Serializes an array as a locale-specific `string`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3 ] );
 
 var str = arr.toLocaleString();
 // returns '1,2,3'
 ```
 
 <a name="method-to-string"></a>
 
 #### Int8Array.prototype.toString()
 
 Serializes an array as a `string`.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2, 3 ] );
 
 var str = arr.toString();
 // returns '1,2,3'
 ```
 
 <a name="method-values"></a>
 
 #### Int8Array.prototype.values()
 
 Returns an iterator for iterating over array elements.
 
 <!-- eslint-disable stdlib/require-globals -->
 
 ```javascript
 var arr = new Int8Array( [ 1, 2 ] );
 
 // Create an iterator:
 var it = arr.values();
 
 // Iterate over array elements...
 var v = it.next().value;
 // returns 1
 
 v = it.next().value;
 // returns 2
 
 var bool = it.next().done;
 // returns true
 ```
