Wrong point of view.

Variables, objects and functions need a **name** to be used,
which **name** points to such variable, object or function.

This **name** can be reassigned, 
as long as they are not created with 'const ..'.

let a1 = 7;
const a2 = 8;

let f1 = (x) => {return x*x};
const f2 = (y) => {return y+y};

let ob1 = {};
const obj2 = {};

The names created with **let** 
can be reassigned to any other type:

let a = 6;

a = (x) => 2*x;
a(7); // 14

a = [33,44];
a[1]; // 44
a[7]; undefined
a(7); Uncaught TypeError: a is not a function
