Answer 3

Actually U have answered the Question yourself ...
The loop you have written in the description is the code to iterate through an array of numbers in Js .

Answer 4

I prefer to use predicate functions to perform any sort of recursive mathematical transformation on a data structure.

My solution uses arrow functions.

const newPrices = prices.map(n => n+amount);

No Steve Sajeev I don't have this intention to teach other but I want just to finish my courses in jscript so it is a way to understand more those topics

HBhZ_C Did you say "JScript" as in JScript, Microsoft's old JavaScript engine. I don't consider it a good choice if you are new to JavaScript. I advise that you first learn standard EcmaScript(ES 2020) before trying out any other implementation.
