copyIndexed

Copy the elements of an indexed array-like object to a new "generic" array.

Installation

npm install @stdlib/array-base-copy-indexed

Usage

var copyIndexed = require( '@stdlib/array-base-copy-indexed' );

copyIndexed( x )

Copies the elements of an indexed array-like object to a new "generic" array.

var x = [ 1, 2, 3 ];

var out = copyIndexed( x );
// returns [ 1, 2, 3  ]

var bool = ( out === x );
// returns false

Notes

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).

Examples

var filledBy = require( '@stdlib/array-filled-by' );
var randu = require( '@stdlib/random-base-randu' );
var copyIndexed = require( '@stdlib/array-base-copy-indexed' );

// Create a Float64Array:
var arr = filledBy( 10, 'float64', randu );

// Copy elements to a generic array:
var out = copyIndexed( arr );

// Retrieve the first element:
var x = out[ 0 ];
// returns <number>

console.log( '%d', x );
