This was my first time using JavaScript. :) I'm not sure about my use of "var" variables in my JavaScript. I've read that you shouldn't really use them, but since "let" and "const" are immutable, I wasn't really sure how to use them for the variables I needed.

    var:

    • function-scoped or globally-scoped
    • can be reassigned

    let:

    • block-scoped
    • can be reassigned

    const:

    • block-scoped
    • cannot be reassigned
    • if a constant is an object, its properties can be updated or removed.
    • if a constant is an array, its items can be updated or removed.
