@stdlib/assert-is-same-array NPM

isSameArray

Test if two arguments are both generic arrays and have the same values.

Installation

npm install @stdlib/assert-is-same-array

Usage

var isSameArray = require( '@stdlib/assert-is-same-array' );

isSameArray( v1, v2 )

Tests if two arguments are both generic arrays and have the same values.

var x = [ 1.0, 2.0 ];
var y = [ 1.0, 2.0 ];
var bool = isSameArray( x, y );
// returns true

bool = isSameArray( x, [ -1.0, 2.0 ] );
// returns false

Notes

In contrast to the strict equality operator ===, the function distinguishes between +0 and -0 and treats NaNs as the same value.

Examples

var isSameArray = require( '@stdlib/assert-is-same-array' );

var x = [ 1.0, 2.0, 3.0 ];
var y = [ 1.0, 2.0, 3.0 ];
var out = isSameArray( x, y );
// returns true

x = [ -0.0, 0.0, -0.0 ];
y = [ 0.0, -0.0, 0.0 ];
out = isSameArray( x, y );
// returns false

x = [ NaN, NaN, NaN ];
y = [ NaN, NaN, NaN ];
out = isSameArray( x, y );
// returns true

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.
