Constant 1/3

What are Constants?

Constants are created just like the var and let. We use the const keyword for initializing constants, for example.

12
const NUMBER = 58; console.log(NUMBER);
copy

Variables declared with const are very much similar to the variables declared with the let keyword, but the only difference is that we cannot reassign values to the variables declared with the const keyword.

123
const PI = 3.141592653589793; PI = 3.14; // error console.log(PI);
copy
