Making JS More Learnable
summary
Khan Academy uses Ace + ProcessingJS to teach JavaScript at scale and reports 200,000 challenges completed and 300,000 unique programs created; linting runs in a web worker and JS Hint gives machine messages that were rewritten into conversational diagnostics, reducing student confusion. Built extras include a baby‑hint spell/case checker and argument‑count rules; browsers and DevTools get suggested fixes for misspelled APIs. The concrete claim is that improving error messages and linters makes novices stick with JavaScript.
