const/let/var:

const/let are block scoped (meaning anywhere we have an opening and closing curly brace we're creating a new scope).

It's generally agreed upon that block scope is a better paradigm than function scope which is why organizations like Mozilla have been primarily using let internally for years. Now that brings us to const. Everything let has, const also has. The only difference is that when you create a variable with const, that variable can't be re-assigned a new reference. Notice I didn't say that variable is immutable.
