Day 04 of JavaScript
Explored operators & type coercion — where JavaScript decides what your data should be, not what it is.

Day 03 of JavaScript 🚀
Fixed my confusion today:
Primitives store actual values (stack)
Objects store references pointing to heap
That’s why object copying behaves differently ��
