You've spent hours wrestling with JavaScript—now your code works… but does it spark joy? Writing clean, readable JavaScript isn't just about aesthetics; it makes debugging easier, collaboration smoother, and future-you much happier.

If reading your own functions feels like deciphering an ancient scroll, it's time to tidy up your JS like a pro! Here's how:

1. Name Variables Like You Mean It

Avoid 'x', 'data', or 'thing'. Use meaningful names:

✅ const userAge = 25;
❌ const x = 25;

Clear names = self-documenting code.

2. Keep Functions Small & Focused

A function should do one thing and do it well. If it's scrolling past 10-15 lines, break it up!

✅ getUser() + formatUserData ()
❌ getAndFormatUserAndSendEmailAndBakeCookies() (too much!)

3. Say Goodbye to Magic Numbers & Strings

Hardcoded values are a nightmare to update. Use constants instead:

✅ const MAX_USERS = 100;
❌ if (users.length > 100) {...}

4. Destructure Like a Boss

Instead of accessing object properties repeatedly, destructure them:

✅ js

const { name, age } = user;

Boom! Cleaner, shorter, better.

5. Use Strict Equality '(===)'

Loose equality '( == )' can cause sneaky bugs. Be strict:

✅ if (score === 10) {...}
❌ if (score == "10") {...} (Oops, type coercion!)
