You made it through the bootcamp. You survived callbacks, tamed the async beast 🐉, and even made peace with the DOM. But if you're still writing 'var', it's time we had a little chat. 😅

'var' is the JavaScript equivalent of using floppy disks in 2025. It's hoisted in strange ways, can leak out of blocks, and generally causes headaches. Now, say hello to 'let' and 'const'—they’re safer, block-scoped, way more predictable, and what all modern codebases expect.

But 'var' isn’t the only habit begging for retirement. Let's talk about a few more:

Still using 'for' loops to loop over arrays? 🔄

Try '.map()', '.forEach()', or '.filter()'—they're cleaner and more expressive.

🧩 Nesting multiple 'if' statements when a guard clause would've saved everyone's brain cells?

Refactor it. Your future self will thank you.

Using magic numbers or hardcoded strings all over your code? 🎲

Give them a name and make your code self-documenting.

🧨 Ignoring error handling because “it works on my machine”?

Not anymore. Real-world code fails—plan for it.

Learning the best practices isn't just about writing code that works—it's about writing code that scales, reads well, and doesn't get you weird looks during code review.

👀 Kadmía helps you unlearn the junk and lock in the good stuff through bite-sized, real-world challenges built for devs who've already done the tutorials and want to actually level up.
