// returns Int8Array

The following array data types are supported:

Data Type	Constructor
int8	`Int8Array`
uint8	`Uint8Array`
uint8_clamped	`Uint8ClampedArray`
int16	`Int16Array`
uint16	`Uint16Array`
int32	`Int32Array`
uint32	`Uint32Array`
float32	`Float32Array`
float64	`Float64Array`
generic	`Array`

Examples

var getCtor = require( 'dstructs-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

$ node ./examples/index.js

Tests

Unit

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

$ make test

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

Test Coverage

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

$ make test-cov
