Native Iterator Helpers Just Shipped. Here's What You Stop Doing

Native iterator helpers have been added to JavaScript, allowing for lazy iteration and reducing memory allocation. This means that you can stop using array chaining methods like filter, map, and slice, and instead use iterator helpers like filter, map, and take. This change is available in Node 22 LTS and later, Bun 1.1.31 and later, Deno 2, and all current Chrome, Firefox, and Safari browsers. To take advantage of this change, use methods like .values() to get an iterator, and then chain iterator helpers like filter, map, and take.
