What is the difference between let, var, and const?

I’m explaining the importance of these three keywords in JavaScript.   

Let see the detail about the - var vs. let vs. const

var: -

1.      var is function-scoped

2.      var returns undefined when accessing a variable before it's declared


let: -

1.      let is block-scoped

2.      let throw ReferenceError when accessing a variable before it's declared



1.      Const is block-scoped

2.      Const throw ReferenceError when accessing a variable before it's declared

3.      Const cannot be reassigned
