    Typed Array Function

    NPM version Build Status Coverage Status

    Return a function which tests if every element in a typed array passes a test condition.

    Installation

    npm install @stdlib/assert-tools-typed-array-function

    Usage

    var typedarrayfcn = require( '@stdlib/assert-tools-typed-array-function' );

    typedarrayfcn( predicate )

    Returns a function which tests if every element in a typed array passes a test condition. Given an input typed array, the function returns true if all elements pass the test and false otherwise.

    var isOdd = require( '@stdlib/assert-is-odd' );
    var Int32Array = require( '@stdlib/array-int32' );
    
    var arr1 = new Int32Array( [ 1, 3, 5, 7 ] );
    var arr2 = new Int32Array( [ 3, 5, 8 ] );
    
    var f = typedarrayfcn( isOdd );
    
    var bool = f( arr1 );
    // returns true
    
    bool = f( arr2 );
    // returns false

    Notes

    • The returned function will return false if not provided a typed array.
    • The returned function will return false if provided an empty typed array.
    • A predicate function should accept a single argument: a typed array element. If the element satisfies a test condition, the predicate function should return true; otherwise, the predicate function should return false.

    Examples

    var isEven = require( '@stdlib/assert-is-even' );
    var Int32Array = require( '@stdlib/array-int32' );
    var typedarrayfcn = require( '@stdlib/assert-tools-typed-array-function' );
    
    var arr1;
    var arr2;
    var bool;
    var f;
    var i;
    
    arr1 = new Int32Array( 25 );
    for ( i = 0; i < arr1.length; i++ ) {
        arr1[ i ] = i;
    }
    
    arr2 = new Int32Array( 25 );
    for ( i = 0; i < arr2.length; i++ ) {
        arr2[ i ] = 2 * i;
    }
    
    f = typedarrayfcn( isEven );
    
    bool = f( arr1 );
    // returns false
    
    bool = f( arr2 );
    // returns true
