Intermediate Algorithm Scripting - DNA Pairing

why does this not work

function pairElement(str) {

  let farr=[];
  let strarr=[[2],[1]];

  strarr.forEach(element => farr.push(element));

  return str;


everywhere i look i see this syntax for foreach

i get an error strarr.forEach is not a function

nevermind sorry , can someone tell me how to delete thread?

So what is the value of strarr after you do this?


There’s nothing wrong with the forEach syntax, but the forEach function works on arrays.

So the above makes no sense anyway: you have written (using the example input at the bottom):

strarr = "GCG".slice("GCG")

What you do think this is going to do?
