Practice a Coding Challenge
Write a single function expression, e.g. function(nums, target) { ... } — it's called with each test's inputs and run in an isolated, time-limited sandbox (a Web Worker), never on the main page.
Write JavaScript, run it against real test cases in an isolated sandbox, and get an instant pass/fail — the same result every time.
