I’m currently learning about let variables and am a little bit confused about ways to use them. What would be a good reason/example to not assign a value to a variable name using let, and then later assign a value to that variable name?

let changeMe = true;
changeMe = false;
console.log(changeMe);
One example I can think of is if you are using the let variable to store ‘string’ data-type, you can just declare the variable without a value, then later you can assign it to string data-type value.
let myString;
myString = "some string";
console.log(myString) //expected output: some string
