Test for deep equality between two values.
var deepEqual = require( '@stdlib/assert/deep-equal' );Returns a boolean indicating if a is deep equal to b.
var bool = deepEqual( [ 1, 2, 3 ], [ 1, 2, 3 ] ); // returns true bool = deepEqual( [ 1, 2, 3 ], [ 1, 2, '3' ] ); // returns false bool = deepEqual( { 'a': 2 }, { 'a': [ 2 ] } ); // returns false- The function uses strict equality checks (
===) and does not perform any type coercion. - When given two objects, only enumerable own properties are recursively compared.
