 ## Usage
 
 ```javascript
 var curryRight = require( '@stdlib/utils/curry-right' );
 ```
 
 #### curryRight( fcn\[, arity]\[, thisArg] )
 
 Transforms a function into a sequence of functions each accepting a single argument.
 
 ```javascript
 function add( x, y ) {
     return x + y;
 }
 
 var fcn = curryRight( add );
 
 var sum = fcn( 2 )( 3 );
 // returns 5
 ```
 
 By default, `arity` is equal to `fcn.length`. For functions without explicit parameters, provide an `arity` argument.
 
 ```javascript
 function add() {
     return arguments[ 0 ] + arguments[ 1 ];
 }
 
 var fcn = curryRight( add, 2 );
 
 var sum = fcn( 2 )( 3 );
 // returns 5
 ```
 
 To specify the curried function execution context, provide a `thisArg` argument.
 
 <!-- eslint-disable no-restricted-syntax -->
 
 ```javascript
 var obj = {
     'name': 'Ada',
     'greet': function greet( word1, word2 ) {
         return word1 + ' ' + word2 + ', ' + this.name + '!';
     }
 };
 
 var fcn = curryRight( obj.greet, obj );
 
 var str = fcn( 'there' )( 'Hello' );
 // returns 'Hello there, Ada!'
 ```
 
 The function supports providing both an `arity` and execution context.
 
 <!-- eslint-disable no-restricted-syntax -->
 
 ```javascript
 var obj = {
     'name': 'Ada',
     'greet': function greet() {
         return arguments[ 0 ] + ' ' + arguments[ 1 ] + ', ' + this.name + '!';
     }
 };
 
 var fcn = curryRight( obj.greet, 2, obj );
 
 var str = fcn( 'there' )( 'Hello' );
 // returns 'Hello there, Ada!'
 ```

 ## Notes
 
 -   Until return value resolution, each invocation returns a new partially applied curry function.
 
     ```javascript
     function add( x, y, z ) {
         return x + y + z;
     }
 
     var fcn = curryRight( add );
 
     var s0 = fcn( 1 )( 2 )( 3 );
     // returns 6
 
     s0 = fcn( -1 )( -2 )( -3 );
     // returns -6
 
     s0 = fcn( 10 )( 20 )( 30 );
     // returns 60
 
     // Return a partially applied curry function:
     var f1 = fcn( 3 );
 
     var s1 = f1( 4 )( 5 );
     // returns 12
 
     s1 = f1( 6 )( 7 );
     // returns 16
 
     s1 = f1( 8 )( 9 );
     // returns 20
 
     // Return a partially applied curry function:
     var f2 = fcn( 4 )( 5 );
 
     var s2 = f2( 6 );
     // returns 15
 
     s2 = f2( 70 );
     // returns 79
 
     s2 = f2( 700 );
     // returns 709
     ```
 
 -   The difference between this function and [`curry`][@stdlib/utils/curry] is the order in which arguments are applied. This function applies arguments starting from the right.

 ## Examples
 
 <!-- eslint no-undef: "error" -->
 
 ```javascript
 var curryRight = require( '@stdlib/utils/curry-right' );
 
 var fcn;
 var out;
 var i;
 
 function add( x, y, z, w, t, s ) {
     return x + y + z + w + t + s;
 }
 
 fcn = curryRight( add );
 out = fcn;
 for ( i = 0; i < add.length; i++ ) {
     out = out( i*10 );
 }
 console.log( out );
