JavaScript Primitives vs Wrapper Objects Explained
Most JavaScript developers use strings, numbers, and booleans every day — but very few understand what happens behind the scenes.
In this video, we break down:
✅ Primitive vs Wrapper Objects
✅ Why "hello" and new String("hello") behave differently
✅ The dangerous new Boolean(false) truthiness trap
✅ Auto-boxing explained simply
✅ Why methods like .toUpperCase() work on primitives
✅ == vs === with wrappers
✅ Performance implications
If you've ever been confused by JavaScript internals or want to level up for interviews, this one is for you.
