Thank you very much, the technique to use an empty string before concat is cool. will use it later.

Amazing, do you have content for object orientated programming in javascript.

Hello Steve, thanks for the previous responses. Regarding the first string. Wouldn't it be var string 1 = new String{"Toy Story"}

When you create a string with new String("Toy Story"); it's an Object, so we can do
str1[15] = " ";
str1[16] = "2";
However when I console.log(String(str1)); I would expect to see Toy Story 2 but all I get is Toy Story. Is it because I'm trying to mutate a string?

Is it correct to say all these strings are identical in every way?

let s1 = new String('Toy')
let s2 = String('Toy')
let s3 = 'Toy'

r1 = s1.toUpperCase()
r2 = s2.toUpperCase()
r3 = s3.toUpperCase()

console.log (s1, s2, s3) // Toy, Toy, Toy
console.log (r1, r2, r3) // TOY, TOY, TOY
