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!
Function sequence.
import funseq from 'https://cdn.jsdelivr.net/gh/stdlib-js/utils-function-sequence@esm/index.mjs';Returns a pipeline function. Starting from the left, the pipeline function evaluates each function and passes the result as an argument to the next function. The result of the rightmost function is the result of the whole.
function a( x ) {
return 2 * x;
}
function b( x ) {
return x + 3;
}
function c( x ) {
return x / 5;
}
var f = funseq( a, b, c );
var z = f( 6 ); // ((2*x)+3)/5
// returns 3Only the leftmost function is explicitly permitted to accept multiple arguments. All other functions are evaluated as unary functions.
function a( x, y ) {
return (x*5) + (y*3);
}
function b( r ) {
return r + 12;
}
var f = funseq( a, b );
var z = f( 4, 6 );
// returns 50- The function will throw if provided fewer than
2input arguments. - The difference between this function and
composeis that this function evaluates input arguments from left-to-right, rather than right-to-left.
