> Returns an array constructor corresponding to an array data type.

Installation

`` bash
$ npm install compute-array-constructors
`

For use in the browser, use browserify.

Usage

` javascript
var getCtor = require( 'compute-array-constructors' );
`

#### getCtor( dtype )

Returns an array constructor corresponding to an array data type.

` javascript
var ctor = getCtor( 'int8' );
// returns Int8Array
`

The following array data types are supported:

| Data Type | Constructor |
|:----------|:------------|
| int8 | [Int8Array][Int8Array] |
| uint8 | [Uint8Array][Uint8Array] |
| uint8_clamped | [Uint8ClampedArray][Uint8ClampedArray] |
| int16 | [Int16Array][Int16Array] |
| uint16 | [Uint16Array][Uint16Array] |
| int32 | [Int32Array][Int32Array] |
| uint32 | [Uint32Array][Uint32Array] |
| float32 | [Float32Array][Float32Array] |
| float64 | [Float64Array][Float64Array] |
| generic | [Array][Array] |

Examples

` javascript
var getCtor = require( 'compute-array-constructors' );

console.log( getCtor( 'int8' ) );
// returns Int8Array

console.log( getCtor( 'uint8' ) );
// returns Uint8Array

console.log( getCtor( 'uint8_clamped' ) );
// returns Uint8ClampedArray

console.log( getCtor( 'int16' ) );
// returns Int16Array

console.log( getCtor( 'uint16' ) );
// returns Uint16Array

console.log( getCtor( 'int32' ) );
// returns Int32Array

console.log( getCtor( 'uint32' ) );
// returns Uint32Array

console.log( getCtor( 'float32' ) );
// returns Float32Array

console.log( getCtor( 'float64' ) );
// returns Float64Array

console.log( getCtor( 'generic' ) );
// returns Array

console.log( getCtor( null ) );
// returns null

console.log( getCtor( 'object' ) );
// returns null

console.log( getCtor( 'array' ) );
// returns null

console.log( getCtor( {} ) );
// returns null

console.log( getCtor( [] ) );
// returns null

To run the example code from the top-level application directory,

` bash
$ node ./examples/index.js
`

Tests

$3

Unit tests use the [Mocha][mocha] test framework with [Chai][chai] assertions. To run the tests, execute the following command in the top-level application directory:

` bash
$ make test
`

All new feature development should have corresponding unit tests to validate correct functionality.

$3

This repository uses [Istanbul][istanbul] as its code coverage tool. To generate a test coverage report, execute the following command in the top-level application directory:

` bash
$ make test-cov
`

Istanbul creates a ./reports/coverage directory. To access an HTML version of the report,

` bash
$ make view-cov
``
