Write a function `removeEWords(sentence)` that accepts a sentence string as an
arg. The function should return a new string, containing only the words that
don't have the letter "e" in them.

Solve this using Array's `filter()` method.


console.log(removeEWords('What time is it everyone?')); // 'What is it'
console.log(removeEWords('Enter the building')); // 'building'

What I have tried:

I've tried numerous things and am just banging my head against the wall.

What I am thinking - If word includes e, slice everything before/after from array then return new array. But if it has more than two words with e that'd destroy everything. I don't know. I've spent WAY too much time on this simple problem and only wish the lesson ahd given better examples/everything I find online doesn't use regex.

let removeEWords = function(sentence) {
    // Your code here
    words = sentence.split(" ");
    newString = '';
    newArray = words.filter(function(word, i, words) {

      if (word.includes('e')) {

Figured it out. Some reason I thought I tied placing the NOT operator before the includes statement but must've only tried to put it before ---> !includes = FAIL.

let removeEWords = function(sentence) {
    // Your code here
    words = sentence.split(" ");
    anArray = [];
    newArray = words.filter(function(word, i, words) {

      if (!word.includes('e')) {
    return anArray.join(" ");

filter[^] returns a new array containing the elements of the original array for which the callback returns true. There is no need to use a third array.
const words = sentence.split(" ");
const newArray = words.filter(w => !w.includes("e"));
return newArray.join(" ");

I didn't refresh my screen, you got in before me! 😆

So instead of voting it down like a douche add your own solution for me to accept. Oh, right, you're an elitist pig.

Insulting the people who are trying to help you is a great way to ensure nobody tries to help you in future. Keep it up, and you'lĺ end up getting kicked off the site.

Just to comment on this, that's not really what the filter() method is for. That method is supposed to return true or false to indicate whether the resulting array should contain that element. In this example you would only need to do:
anArray = words.filter(word => !word.includes('e'));
