Does variables declared with let and const gets hoisted?
Answer is YES!
let & const variables are also hoisted but they are not initialized with a value.
This certain phase when let and const variables are hoisted and are not initialized yest is called Temporal Dead Zone.
When variables are in Temporal Dead Zone they cannot be accessed.
That's why it throws ReferenceError: cannot access [variable name] before it's initialization.
const is a signal that the identifier won’t be reassigned.
let is a signal that the variable may be reassigned, such as a counter in a loop, or a value swap in an algorithm. It also signals that the variable will be used only in the block it’s defined in, which is not always the entire containing function.
var is now the weakest signal available when you define a variable in JavaScript. The variable may or may not be reassigned, and the variable may or may not be used for an entire function, or just for the purpose of a block or loop.
