Test if an array is sorted in ascending order.

Usage

var isSortedAscending = require( '@stdlib/array/base/assert/is-sorted-ascending' );

isSortedAscending( x )

Tests if an array is sorted in ascending order.

var out = isSortedAscending( [ 1, 2, 3 ] );
// returns true

out = isSortedAscending( [ 3, 2, 1 ] );
// returns false

If provided an empty array, the function returns false.

var out = isSortedAscending( [] );
// returns false

Examples

var AccessorArray = require( '@stdlib/array/base/accessor' );
var isSortedAscending = require( '@stdlib/array/base/assert/is-sorted-ascending' );

var x = new AccessorArray( [ 1, 2, 3, 4 ] );
var bool = isSortedAscending( x );
// returns true

x = new AccessorArray( [ 1, 1, 1, 1 ] );
bool = isSortedAscending( x );
// returns true

x = new AccessorArray( [ 1 ] );
bool = isSortedAscending( x );
// returns true

x = new AccessorArray( [ 1, 3, 2, 4 ] );
bool = isSortedAscending( x );
// returns false

x = new AccessorArray( [ 4, 3, 2, 1 ] );
bool = isSortedAscending( x );
// returns false
