Array Function
Return a function which tests if every element in an array passes a test condition.
Installation
npm install @stdlib/assert-tools-array-function
Usage
var arrayfcn = require( '@stdlib/assert-tools-array-function' );
arrayfcn( predicate )
Returns a function which tests if every element in an array
passes a test condition. Given an input array
, the function returns true
if all elements pass the test and false
otherwise.
var isOdd = require( '@stdlib/assert-is-odd' );
var arr1 = [ 1, 3, 5, 7 ];
var arr2 = [ 3, 5, 8 ];
var f = arrayfcn( isOdd );
var bool = f( arr1 );
// returns true
bool = f( arr2 );
// returns false
Notes
- The returned function will return
false
if not provided anarray
. - The returned function will return
false
if provided an emptyarray
. - A
predicate
function should accept a single argument: anarray
element. If thearray
element satisfies a test condition, thepredicate
function should returntrue
; otherwise, thepredicate
function should returnfalse
.
Examples
var isEven = require( '@stdlib/assert-is-even' );
var arrayfcn = require( '@stdlib/assert-tools-array-function' );
var arr1;
var arr2;
var bool;
var f;
var i;
arr1 = new Array( 25 );
for ( i = 0; i < arr1.length; i++ ) {
arr1[ i ] = i;
}
arr2 = new Array( 25 );
for ( i = 0; i < arr2.length; i++ ) {
arr2[ i ] = 2 * i;
}
f = arrayfcn( isEven );
bool = f( arr1 );
// returns false
bool = f( arr2 );
// returns true
