- this & Arrow Functions in JS
-this depends on how a function is called
- Arrow functions inherit this (lexical scope)
- Node.js → this = {} | Browser → this = window
- Explicit return → {} | Implicit return → no {}

Scope & Hoisting in JS
🔹 Inner → can access outer vars
🔹 Outer → can’t access inner vars
🔹 Function declarations → hoisted
🔹 Function expressions / arrow → not hoisted
Know your scopes to avoid tricky bugs!
