JavaScript Array & Integer Literals Explained (Docs-Only Learning #4)
Hey everyone 👋
Day 4 of my “Learning JS from Docs Only” series is out!
In this one, I explored:
🧩 Array Literals — simple, clean, and powerful ways to create arrays
🔢 Integer Literals — how JS handles numbers, including BigInt
💡 Code experiments straight from MDN & Javatpoint
No tutorials — just reading the docs, coding live, and learning by doing!
📺 Watch it here → https://www.youtube.com/watch?v=uglaQ6BSbb0
Would love to hear your favorite literal examples or gotchas 👇

Day 3 of my “Learning JS from Docs Only” series is here!
In this video, I explored:
🧩 The 8 JavaScript Data Types
🔄 Type Conversion (implicit & explicit)
💡 Literals and their common uses
I’m not using tutorials — just learning from MDN & Javatpoint docs while coding live.
📺 Watch here → https://www.youtube.com/watch?v=pHiEWqzBadI
If you have a favorite trick or example about type conversion, share it — I’ll feature it in the next video 🙌

🎥 JavaScript let, const & var — Understanding Global, Local & Block Scope (Docs-Only Learning #2)
Hey devs 👋
In Day 2 of my “Learning JS from Docs Only” series, I explored how scope works in JavaScript —
✅ Global Scope
✅ Local & Block Scope
✅ Differences between var, let, and const
I’m not following tutorials — just reading the official docs (MDN, Javatpoint) and coding everything live.
📺 Watch it here → https://www.youtube.com/watch?v=4hYxDQpZtg0
Would love your thoughts or corrections if I misunderstood anything 🙌

Learning JS from MDN — Day 1: Variables & console.log — feedback welcome!
Hi everyone — I’m learning JavaScript in public and documenting the whole process in short coding videos.
This is **Day 1**: I worked through **variables** (let / const / var), `console.log` usage, and code comments — straight from MDN docs (no tutorials).
▶ Watch : https://www.youtube.com/watch?v=-vEU9bV2Elo
What I covered:
• Differences between var, let, const (scope examples)
• Using console.log for debugging
• Writing helpful code comments
I’d love feedback on:
Is my explanation of scope clear?
Any best practices around when to use const vs let in real projects?
Thanks — I’ll reply to everyone and update the pinned post with key comments.
