The split method turns a string into an array. In the case of alphabet below, each letter of the string is being turned

Hey! i'm stuck in this exercises and i try a lot of different solutions but i can't find how to remove the letter 'L' in an Array with forEach

Thanks in advance for the help

app.js 
const alphabet = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'.split('');
let noel = [];

// noel should be: ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J', 'K', 'M', 'N', 'O', 'P', 'Q', 'R', 'S', 'T', 'U', 'V', 'W', 'X', 'Y', 'Z']
// Write your code below

alphabet.forEach(alphabets => {
  if(alphabets.charAt(0) === 'L') {
    noel.push(alphabet);
  }
});

Hi there, Yannis Bouacida ! It seems like you're on the right path but there are two things going wrong here. First, your comparison is incorrect. You are checking to see if the letter is "L". If it is, push it to the noel array. But this is exactly backward. We want to push in everything that is not equal to "L". So where you have === "L" you will need != "L".

Secondly, you chose to name the individual letter alphabets. I might have chosen a different name here to make it more clear that it is an individual letter from the alphabet. But ultimately, the variable name doesn't really matter. Here's the part that does matter though:

You wrote...

noel.push(alphabet);

But you meant to write...

noel.push(alphabets);

Remember, alphabet is the array of letters while alphabets is the individual letter being considered.

Hope this helps! :sparkles:
