Returns a new array iterator object that contains the values for each index in the array
Syntax

A new iterable iterator object
Examples
const arr = ['a', 'b', 'c'];
for (const value of arr.values()) {
console.log(value);
}
// 'a', 'b', 'c'const numbers = [10, 20, 30];
const vals = [...numbers.values()];
console.log(vals); // [10, 20, 30]const arr = [1, 2, 3];
const iter = arr.values();
console.log(iter.next()); // { value: 1, done: false }Understanding Array.prototype.values
The Array.prototype.values method in JavaScript returns a new array iterator object that contains the values for each index in the array. It belongs to the Array object and is one of the most widely used methods for working with array values in modern JavaScript and TypeScript applications.
The method signature is array.values(). When called, it returns a new iterable iterator object. Understanding when and how to use values() helps you write more expressive, readable code.
Common use cases for Array.prototype.values include data transformation, input validation, API response processing, and building reusable utility functions. It works well alongside related methods like array-keys, array-entries, object-values, enabling you to chain operations together for complex data manipulation pipelines.
Browser support for Array.prototype.values is excellent across all modern browsers including Chrome, Firefox, Safari, and Edge. It is also fully supported in Node.js and Deno. For older environments, transpilation with Babel or a polyfill may be needed.
Browser Compatibility
Supported in all modern browsers (Chrome, Firefox, Safari, Edge) and Node.js. Part of the ECMAScript standard.
