return value inside foreach

Question

So this is very weird, I have a foreach function like this:

  let cookieValue = \'\';

  cookieList.forEach(function(cookieItem) {
    const cookieParts = co         


        

Answer 1

Your return value in the forEach function return in that function. By placing the return in the outer function, you return that value when that function is called. See this simplified example.

function x(){
    function y(){
        return 5 // Does not return in the x function
    }
    y() // = 5
    return 7
}
x() // =7

You seem like you are looking for Array.find.

let cookieValue = '';
return cookieList.find(function(cookieItem) {
  const cookieParts = cookieItem.split('=');
  const value = cookieParts[1];
  const key = cookieParts[0];
  return key.trim() === cookieName
});
