Hi Jaexus

Are you looking for further explanations of how a strings length is determined?

Or is this code giving you an error?

I got an error running the code for reusing a variables name. Using unique variable names would fix that.

3

You try to redeclare the variable, when you want to reassign it’s value

4

I get this error when I run that code

Uncaught SyntaxError: Identifier 'lastNameLength' has already been declared

let lastNameLength = 0;

// ...

let lastNameLength = lastName.length;

If your updating the value, just drop the second let keyword, it only needs to be declared once.

let lastNameLength = 0;

// ...

lastNameLength = lastName.length;
