🔸Function Expression:🔸
Function Expression ka matlab hai jab hum ek function ko kisi variable ke saath assign karte hain.
Jaise:

const greet = () => console.log("Hi");

Isme greet ek variable hai jo ek function ko hold kar raha hai. Function Expressions ko hoist nahi kiya jata, iska matlab hai ki aap inhe declare karne se pehle call nahi kar sakte.

Agar aap aisa karte hain, toh error aayega kyunki variable hoist hota hai, lekin uska value assign nahi hota jab tak code us line tak nahi pahuchta.

🔸Hoisting:🔸
Hoisting ka matlab hai ki JavaScript mein functions aur variables ko unke scope ke top par le jaya jata hai.

Function declarations poori tarah se hoist hoti hain, matlab unka naam aur body dono upar le jaye jate hain.

Isliye aap function ko uske declare hone se pehle bhi call kar sakte ho. Lekin agar aap function expression use karte ho, jaise const ya let ke saath, toh sirf variable declaration hoist hoti hai, assignment nahi.

Is wajah se aapko "Cannot access before initialization" error milta hai.

Stop letting AI guess your UI. 🎨

It’s now possible to build with the design systems of top brands using just a single DESIGN .md file. 
What is it?
A DESIGN .md file is a machine-readable Markdown document introduced by Google Stitch that defines your UI rules—colors, typography, and spacing—in a format AI actually understands. 

The Workflow:
Pick a style: Find a brand you love.
Install: Add the DESIGN .md file to your project root.
Build: Use it with AI coding agents like Claude, Cursor, or Aider to generate perfectly consistent UI every time. 

Instead of random layouts, your AI now has a source of truth.
👉 Explore the collection at getdesign.md (or the Awesome DESIGN repo).
