Answer 2

You can get useful Answers of your question via single web search as Lothar mentioned. but still here is the difference

Var(Variable): Variable is like a container it which we store values
Const: it a keyword use to make a variable value const mean you can't change it anymore if try to it will occur an error

Answer 3

It's quite different, let me explain:
var = function-scoped, can be redeclared and updated, hoisted, but undefined before use

let = lock-scoped, can't be redeclared in the same scope, but can be updated

const = block-scoped, can't be redeclared or updated, immutable reference, but object properties can still change

Also just my suggestion, use let and const in modern JavaScript , avoid var

Answer 4

let = modern way of declaring variables

const = modern way of declaring variables whose value cannot be changed

You don't have to know the meaning of var. I have never used it before

Answer 6

All three can be used to declare variables of any type. However, var and let allow for reassignment of values, whereas const doesn’t because const is immutable. Also, var allows for “hoisting” which means it’s not limited in scope, whereas let and const don’t allow hoisting.

Happy coding.
