uint16	Uint16Array
int32	Int32Array
uint32	Uint32Array
float32	Float32Array
float64	Float64Array
generic	Array

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( '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( {} ) );

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

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

$ 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

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

$ make view-cov
