I’m trying to loop through an array and if there are any matching elements, it should push true to a new array else return false.
const wordPerformance = [] const wordsReviewed = "candy, cattle, cat, call, cheat"; const wordsIncorrect = "candy, cattle, call, cheat"; wordsReviewed.split(/,s?/).forEach((word) => { if (wordsIncorrect.includes(word)) { wordPerformance.push(false); } else { console.log(word) //unreachable, though 'cat' should be logged wordPerformance.push(true); } }); console.log(wordPerformance);
By this logic, wordPerformance should return
[false, false, true, false, false]
however, it is returning
[false, false, false, false, false]
Maybe there is something I’m not seeing?

You have to first split the wordsIncorrect
string the same way you did it with the wordsReviewed
so it does compare whith the item and not include strings which have something at the end like matching “cat” with “cattle”
This is the fixed example
const wordPerformance = [] const wordsReviewed = "candy, cattle, cat, call, cheat"; const wordsIncorrect = "candy, cattle, call, cheat"; const wordsIncorrectSplitted = wordsIncorrect.split(/,s?/); wordsReviewed.split(/,s?/).forEach((word) => { if (wordsIncorrectSplitted.includes(word)) { wordPerformance.push(false); } else { console.log(word) //unreachable, though 'cat' should be logged wordPerformance.push(true); } }); console.log(wordPerformance);
