Intermediate Algorithm Scripting - Sum All Numbers in a Range

Tell us what’s happening:
any bugs?

Your code so far

function sumAll(arr) {
  let firstTerm = Math.min(...arr);
  let lastTerm = Math.max(...arr);
  if(firstTerm = lastTerm){
    return firstTerm;
  } else{
    return sumAll([firstTerm, lastTerm - 1]) + lastTerm;

console.log(sumAll([1, 4]));

You should know this since it isn’t passing :slight_smile:

Hint: How many equal signs do you need to check for equality?


thank you very much sir


It is great that you solved the challenge, but instead of posting your full working solution, it is best to stay focused on answering the original poster’s question(s) and help guide them with hints and suggestions to solve their own issues with the challenge.

We are trying to cut back on the number of spoiler solutions found on the forum and instead focus on helping other campers with their questions and definitely not posting full working solutions.
