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) {
words = sentence.split(" ");
anArray = [];
newArray = words.filter(function(word, i, words) {
if (!word.includes('e')) {
anArray.push(word)
}
}
)
return anArray.join(" ");
};
