EPISODE 5 – Closures

Closures are one of the most important — and most misunderstood — concepts in JavaScript.

This video explains closures simply and practically. A closure allows an inner function to remember and access variables from its outer function, even after the outer function has finished executing. This behavior makes closures powerful for managing state, creating private variables, and building reusable helpers.

This video covers:

• What closures are in JavaScript
• How inner functions retain access to outer variables
• Real-world use cases like counters and data privacy
• Why are closures frequently asked in JavaScript interviews

If you can clearly explain closures, it shows strong fundamentals and a real understanding of JavaScript — not just surface-level syntax.
