## Usage | ||
|
||
```javascript | ||
var hasEqualValuesIndexed = require( '@stdlib/array/base/assert/has-equal-values-indexed' ); | ||
``` | ||
|
||
#### hasEqualValuesIndexed( x, y ) | ||
|
||
Tests if two indexed arrays have equal values. | ||
|
||
```javascript | ||
var x = [ 0, 0, 1, 0 ]; | ||
var y = [ 0, 0, 1, 0 ]; | ||
|
||
var bool = hasEqualValuesIndexed( x, y ); | ||
// returns true | ||
``` | ||

<section class="notes"> | ||
|
||
## 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`][@stdlib/array/complex64] and [`Complex128Array`][@stdlib/array/complex128]). | ||

var hasEqualValuesIndexed = require( '@stdlib/array/base/assert/has-equal-values-indexed' ); | ||
|
||
var buf = discreteUniform( 10, 0, 10 ); | ||
// returns <Float64Array> | ||
|
||
var x = new Float64Array( buf ); | ||
// returns <Float64Array> | ||
|
||
var y = new Float64Array( buf ); | ||
// returns <Float64Array> | ||

var out = hasEqualValuesIndexed( x, y ); | ||

{{alias}}( x, y ) | ||
Tests if two indexed arrays have equal values. | ||
|
||
If provided arrays of unequal length, the function returns `false`. | ||
|
||
Parameters | ||
---------- | ||
x: Array|TypedArray|Object | ||
First input array. | ||
|
||
y: Array|TypedArray|Object | ||
Second input array. | ||
|
||
Returns | ||
------- | ||
bool: boolean | ||
The function returns `true` if both arrays have equal values; otherwise, | ||
the function returns `false`. | ||
|
||
Examples | ||
-------- | ||
> var x = [ 0, 0, 1, 0 ]; | ||
> var y = [ 0, 0, 1, 0 ]; | ||
> var out = {{alias}}( x, y ) | ||
true | ||
