Basic Javascript - how to remove a comma from the string

Question

I have a question that is consuming me here concerning this little piece of code:

let word = "APPLE"
//CONVERTED TO ARRAY
let res = word.slice(3,5)
//RES = LE
let res1 = res.split("")
//REVERSE THE ARRAY NOW IS "E,L"
let res2 = res1.reverse()
//MERGE INTO A STRING
let res3 = res2.toString()
//FINALLY RETURN INTO "E L"

I want you to go out on the "E L" console, instead of "E,L," I want a space between the lyrics, I tried a lot of method and I couldn’t, please if anyone can help me I would be very grateful

Answer 1

You must have used the .join('') wrong.

let res2 = ["E", "L"]
let res3 = res2.join(' ')
console.log(res3)

Functional code above.
