You've should use const keyword. It similar to let keyword but not the same.
By declaring with const keyword it's value can only be Read by user and cannot be modified. It does not allow to change it's value to change through reassignment and it cannot be redeclared.
If you declare data types with const keyword object and arrays, it's properties or items can be updated or removed.
if you try to reassign the constant variable it will throw an error.
let num1 = 1;
const num2 = 1;
console.log(num1);
num1 = 2;
console.log(num1);
console.log(num2);
num2 = 2;
console.log(num2);
