Create a zero-filled array having a specified length.
npm install @stdlib/array-zerosWe 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 a specified length.
``bash`
npm install @stdlib/array-zeros
`javascript`
var zeros = require( '@stdlib/array-zeros' );
#### zeros( length\[, dtype] )
Creates a zero-filled array having a specified length.
`javascript`
var arr = zeros( 2 );
// returns
The function recognizes 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 to 0-255
- : generic JavaScript values
By default, the output array data type is float64 (i.e., a [typed array][mdn-typed-array]). To specify an alternative data type, provide a dtype argument.
`javascript`
var arr = zeros( 2, 'int32' );
// returns
`javascript
var dtypes = require( '@stdlib/array-dtypes' );
var zeros = require( '@stdlib/array-zeros' );
// Get a list of array data types:
var dt = dtypes();
// Generate zero-filled arrays...
var arr;
var i;
for ( i = 0; i < dt.length; i++ ) {
arr = zeros( 4, dt[ i ] );
console.log( arr );
}
