About stdlib...
We 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!
pickArguments
Create a function that invokes a provided function with specified arguments.
Installation
1npm install @stdlib/utils-pick-arguments
Usage
1var pickArguments = require( '@stdlib/utils-pick-arguments' );
pickArguments( fcn, indices[, thisArg] )
Returns a function that invokes a provided function with specified arguments.
1function foo( a, b ) { 2 return [ a, b ]; 3} 4 5var bar = pickArguments( foo, [ 0, 2 ] ); 6 7var out = bar( 1, 2, 3 ); 8// returns [ 1, 3 ]
To set the this context when invoking the provided function, provide a thisArg.
1function Foo() { 2 this.x = 1; 3 this.y = 2; 4} 5 6Foo.prototype.scale = function scale( a, b ) { 7 return [ this.x*a, this.y*b ]; 8}; 9 10var ctx = { 11 'x': 10, 12 'y': 20 13}; 14 15var foo = new Foo(); 16 17var bar = pickArguments( foo.scale, [ 0, 2 ], ctx ); 18 19var out = bar( 1, 2, 3 ); 20// returns [ 10, 60 ]
Examples
1var filledarrayBy = require( '@stdlib/array-filled-by' ); 2var add = require( '@stdlib/math-base-ops-add' ); 3var pickArguments = require( '@stdlib/utils-pick-arguments' ); 4 5function fill( i ) { 6 return i; 7} 8 9// Create a data array: 10var x = filledarrayBy( 10, 'float64', fill ); 11 12// Compute the sum of consecutive elements... 13var f; 14var i; 15for ( i = 1; i < x.length; i++ ) { 16 f = pickArguments( add, [ i-1, i ] ); 17 console.log( 'sum(x_%d, x_%d) = %d', i-1, i, f.apply( null, x ) ); 18}
