var declarations are globally scoped or function scoped while let and const are block scoped. var variables can be updated and re-declared within its scope; let variables can be updated but not re-declared; const variables can neither be updated nor re-declared. They are all hoisted to the top of their scope. Better understanding with examples =>https://codeburst.io/learn-let-var-and-const-in-easiest-way-with-guarantee-e6ecf551018a
