Using .filter to compare two arrays and return values that aren't matched

rated 0 times [ 12] [ 3] / answers: 1 / hits: 54474 / 7 Years ago, wed, august 9, 2017, 12:00:00

I'm having some issues comparing the elements of two arrays and filtering out matching values. I only want to return array elements that are NOT included within wordsToRemove.

var fullWordList = ['1','2','3','4','5'];

var wordsToRemove = ['1','2','3'];



var filteredKeywords = fullWordList.forEach(function(fullWordListValue) {

    wordsToRemove.filter(function(wordsToRemoveValue) {

        return fullWordListValue !== wordsToRemoveValue

    })

});



console.log(filteredKeywords);

You can use filter and includes to achieve this:

var fullWordList = ['1','2','3','4','5'];

var wordsToRemove = ['1','2','3'];



var filteredKeywords = fullWordList.filter((word) => !wordsToRemove.includes(word));



console.log(filteredKeywords);
