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!

hasEqualValuesIndexed

NPM version Build Status Coverage Status

Test if two indexed arrays have equal values.

Usage

To use in Observable,

hasEqualValuesIndexed = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/array-base-assert-has-equal-values-indexed@umd/browser.js' )

To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:

var hasEqualValuesIndexed = require( 'path/to/vendor/umd/array-base-assert-has-equal-values-indexed/index.js' )

To include the bundle in a webpage,

<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/array-base-assert-has-equal-values-indexed@umd/browser.js"></script>

If no recognized module system is present, access bundle contents via the global scope:

<script type="text/javascript">
(function () {
    window.hasEqualValuesIndexed;
})();
</script>

hasEqualValuesIndexed( x, y )

Tests if two indexed arrays have equal values.

var x = [ 0, 0, 1, 0 ];
var y = [ 0, 0, 1, 0 ];

var bool = hasEqualValuesIndexed( x, y );
// returns true

Notes

  • If provided arrays of unequal length, the function returns false.
  • The function performs strict equality comparison.
  • The function does not skip undefined elements and is thus not optimized for sparse arrays.
  • An indexed array-like object is a data structure in which one retrieves elements via integer indices using bracket [] notation (e.g., Float64Array, Int32Array, Array, etc). This is in contrast to an accessor array-like object in which one retrieves elements using get and set methods (e.g., Complex64Array and Complex128Array).

Notice

This package is part of 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.
