What concepts does the JavaScript Mastery skill cover?

It covers over 33 essential concepts including primitive types, type coercion, closures, hoisting, the event loop, Promises, async/await, and prototypal inheritance.

Does it support the latest JavaScript standards?

Absolutely. It includes guidance on modern ES6+ features like destructuring, the spread/rest operators, nullish coalescing, and optional chaining.

How does this skill help with JavaScript debugging?

It provides deep technical explanations for common pitfalls like 'this' binding, scope issues, and the execution order of microtasks versus macrotasks.

Is this skill suitable for senior developers?

Yes, it serves as a high-level reference for advanced patterns such as functional composition, currying, and complex object manipulation methods.
