About this tool
JavaScript arrays expose dozens of methods. This chooser maps common goals to the method that usually fits, with mutating vs non-mutating badges and modern alternatives like toSorted,Object.groupBy, and Array.fromAsync.
Everything runs in your browser. Goal and method selections sync to the URL so you can share a link.
