How do I remove an element in a list, using forEach?

Question

var people = [\'alex\',\'jason\',\'matt\'];

people.forEach(function(p){
    if(p.length > 4){
       //REMOVE THIS PERSON or pop it out of the list or whatever
          


        

Answer 1

You shouldn't modify the array you're looping on. You can produce a new one, though:

var newPeople = [];
people.forEach(function(p){
    if(p.length <= 4){
        newPeople.push(p);
    }
});

Why you shouldn't modify array you're looping.
