Dear JavaScript...
summary
Covers why JavaScript feels both powerful and confusing by connecting event loop behavior, scoping and first-class functions to real code patterns: explains that non-blocking applies to I/O only and shows a CPU-bound while loop up to Number.MAX_SAFE_INTEGER blocks CPU-bound loops (30 minutes on MacBook), demonstrates the classic for+setTimeout closure puzzle, notes Promises use microtasks/jobs, recommends MDN and You Don’t Know JS, shows practical currying like use closures to cache expensive rates (convert pound→euro) and points out Node uses libuv with 4 threads for I/O.
