🚨 JAVASCRIPT HAS A REAL BUG! 🚨

Open your console and type:

typeof null

You'll get:

'object'

That's wrong—null is not an object!

🔍 How did this happen?
When JavaScript was first implemented, values were stored in a tagged format, where the lower bits determined the type:
- Objects had a type tag of 0.
- null was stored as 0 in memory.

Since null had 0 in its type tag, typeof mistakenly classified it as an "object".

🔧 Why isn't it fixed?
One word: Backward compatibility.
Fixing it would break too many apps, so it's here to stay!

💬 Share this with JavaScript haters new (Lovers)... Lmao

Does anyone know a coffee shop or workspace with decent WiFi? I'm on an unlimited 5G plan, but the network's acting like it's powered by a potato—87kbps right now.
