01JavaScript Language Fundamentals and Vendor-Neutral Certification Scope
This domain covers the ECMAScript language itself, not browser DOM or Node.js APIs. Expect short snippets where you must predict output, explain coercion, or identify why a closure or this binding behaves as it does. The certification is vendor-neutral, so answers should rely on standard language semantics rather than a specific runtime. JavaScript has seven primitive types-string, number, bigint, boolean, undefined, symbol, and null-plus objects.

- Practice questionsWhich declaration creates a block-scoped binding that cannot be reassigned after initialization?
- Flashcardsvar hoisting behavior. A var declaration is hoisted to the top of its function and initialized to undefined, so reading it before the assignment line yields undefined rather than throwing an error.
- Cheat sheetvar is function-scoped and hoisted with an initial value of undefined ; let and const are block-scoped and hoisted but stay in the temporal dead zone until their declaration executes, so access before that point throws a ReferenceError .
- Key termsPrimitive value. One of the immutable building-block data types: string, number, bigint, boolean, undefined, symbol, or null.
- Study planMap the vendor-neutral certification scope by listing every exam objective area and marking each as known, shaky, or unknown.
- Common mistakesCandidates learn 'always use ===' as a slogan, so they cannot predict what 0 == '' , null == undefined , or [] == false evaluate to, and they miss the one idiom where == is intentional ( x == null matches both null and undefined).
