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!
Create a zero-filled array having the same length and data type as a provided array.
import zerosLike from 'https://cdn.jsdelivr.net/gh/stdlib-js/array-zeros-like@esm/index.mjs';Creates a zero-filled array having the same length and data type as a provided array x.
var x = [ 1, 2, 3, 4, 5 ];
var arr = zerosLike( x );
// returns [ 0, 0, 0, 0, 0 ]The function supports the following data types:
float64: double-precision floating-point numbers (IEEE 754)float32: single-precision floating-point numbers (IEEE 754)complex128: double-precision complex floating-point numberscomplex64: single-precision complex floating-point numbersint32: 32-bit two's complement signed integersuint32: 32-bit unsigned integersint16: 16-bit two's complement signed integersuint16: 16-bit unsigned integersint8: 8-bit two's complement signed integersuint8: 8-bit unsigned integersuint8c: 8-bit unsigned integers clamped to0-255generic: generic JavaScript values
By default, the output array data type is inferred from the provided array x. To return an array having a different data type, provide a dtype argument.
var x = [ 0, 0 ];
var arr = zerosLike( x, 'int32' );
// returns <Int32Array>[ 0, 0 ]<!DOCTYPE html>
