Memory Allocation
JS Tutor:
Variables are containers for storing data values. In modern JavaScript, we use 'let' and 'const' to declare them.
The Basics of Storage
const
Short for constant. Use this by default unless you know the value will change.
let
Use this for values that will be updated, like counters or toggles.
var
The legacy way. Avoid using this in modern code due to scope issues.
