JS: Array.prototype.values

By Xah Lee. Date: 2018-01-01. Last updated: 2020-09-13.

New in JS2015.

arrayX.values(): Return a Iterator (also is a Iterable Object), each entry is the element's value of the array.

Note: this method is not useful, because array itself is a iterable already.

as of 2018-01-01 Array.prototype.values is not supported by Google Chrome, Firefox. It's supported in both as of 2019-10-31.

for (const e of ["a", "b", "c"].values()) { console.log( e ); }

// prints
// a
// b
// c

Array.prototype[Symbol.iterator]

Array.prototype.values is identical to Array.prototype[Symbol.iterator]

console.log( 
Array.prototype.values
===
Array.prototype [ Symbol.iterator ]
); // true
