 ## Usage
 
 ```javascript
 var uncurryRight = require( '@stdlib/utils/uncurry-right' );
 ```
 
 #### uncurryRight( fcn\[, arity]\[, thisArg] )
 
 Transforms a curried function into a function invoked with multiple arguments.
 
 <!-- eslint-disable no-restricted-syntax -->
 
 ```javascript
 function add( y ) {
     return function add( x ) {
         return x + y;
     };
 }
 
 var fcn = uncurryRight( add );
 
 var sum = fcn( 3, 2 );
 // returns 5
 ```
 
 To enforce a fixed number of parameters, provide an `arity` argument.
 
 <!-- run throws: true -->
 
 <!-- eslint-disable no-restricted-syntax -->
 
 ```javascript
 function add( y ) {
     return function add( x ) {
         return x + y;
     };
 }
 
 var fcn = uncurryRight( add, 2 );
 
 var sum = fcn( 9 );
 // throws <Error>
 ```
 
 To specify an execution context, provide a `thisArg` argument.
 
 <!-- eslint-disable no-invalid-this -->
 
 ```javascript
 function addY( y ) {
     this.y = y;
     return addX;
 }
 
 function addX( x ) {
     return x + this.y;
 }
 
 var fcn = uncurryRight( addY, {} );
 
 var sum = fcn( 3, 2 );
 // returns 5
 ```
 
 The function supports providing both an `arity` and execution context.
 
 <!-- run throws: true -->
 
 <!-- eslint-disable no-invalid-this -->
 
 ```javascript
 function addY( y ) {
     this.y = y;
     return addX;
 }
 
 function addX( x ) {
     return x + this.y;
 }
 
 var fcn = uncurryRight( addY, 2, {} );
 
 var sum = fcn( 3, 2 );
 // returns 5
 
 sum = fcn( 4 );
 // throws <Error>
 ```

 ## Notes
 
 -   The difference between this function and [`uncurry`][@stdlib/utils/uncurry] is the order in which arguments are applied. This function applies arguments starting from the right.

 ## Examples
 
 <!-- eslint no-undef: "error" -->
 
 ```javascript
 var fromCodePoint = require( '@stdlib/string/from-code-point' );
 var curryRight = require( '@stdlib/utils/curry-right' );
 var uncurryRight = require( '@stdlib/utils/uncurry-right' );
 
 var uncurried;
 var curried;
 var abcs;
 var out;
 var a;
 var i;
 
 function concat() {
     var len;
     var out;
     var i;
 
     len = arguments.length;
     out = '';
     for ( i = 0; i < len; i++ ) {
         out += arguments[ i ];
         if ( i < len-1 ) {
             out += ',';
         }
     }
     return out;
 }
 
 // Character codes:
 a = 97;
 
 abcs = new Array( 26 );
 for ( i = 0; i < abcs.length; i++ ) {
     abcs[ i ] = fromCodePoint( a + i );
 }
 out = concat.apply( null, abcs );
 // returns 'a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z'
 
 // Transform `concat` into a right curried function:
 curried = curryRight( concat, 26 );
 
 out = curried;
 for ( i = abcs.length-1; i >= 0; i-- ) {
     out = out( abcs[ i ] );
 }
 console.log( out );
 // => 'a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z'
 
 // Uncurry a right curried function:
 uncurried = uncurryRight( curried );
 
 out = uncurried.apply( null, abcs );
 // returns 'a,b,c,d,e,f,g,h,i,j,k,l,m,n,o,p,q,r,s,t,u,v,w,x,y,z'
