VAR was the King. We used var in everywhere we wants to declare a variable
var variables can be re-declared and updated
Now we divide var with two different types one CONST & other LET
CONST is declared for those value which will not changed anytime! Or will not be updated at any point.
const cannot be updated or re-declared, this will lead you to an error you if try
We use LET when their is a change of updating the variable
LET can be updated but not re-declared. This will give a error you can’t run code
So in es6 we use LET & CONST not Var!
Do you knew this before ?
