Partially apply function arguments.
npm install @stdlib/utils-papplyWe believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js. The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases. When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there. To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

> Partially apply function arguments.
``bash`
npm install @stdlib/utils-papply
`javascript`
var papply = require( '@stdlib/utils-papply' );
#### papply( fcn\[, ...args] )
Partially applies function arguments.
`javascript
function add( x, y ) {
return x + y;
}
var add2 = papply( add, 2 );
var sum = add2( 3 );
// returns 5
sum = add2( 7 );
// returns 9
`
- The implementation does not set the length of the returned function. Accordingly, the returned function length is always 0.null
- The evaluation context is always .
`javascript
var randu = require( '@stdlib/random-base-randu' );
var floor = require( '@stdlib/math-base-special-floor' );
var papply = require( '@stdlib/utils-papply' );
var fcn;
var w;
var t;
var s;
var v;
var i;
function add( x, y, z, w, t, s ) {
return x + y + z + w + t + s;
}
fcn = papply( add, 5, 4, 3 );
for ( i = 0; i < 100; i++ ) {
w = floor( randu() * 5 );
t = floor( randu() * 10 );
s = floor( randu() * 15 );
v = fcn( w, t, s );
console.log( '5+4+3+%d+%d+%d = %d', w, t, s, v );
}

This package is part of [stdlib][stdlib], a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
