How To Determine If A Number Is Even Using Bracket Notation

1

I’m wanting to go through the object and delete any even numbers, but I keep getting an error where I can’t do the following: if (obj[currentValue] % 2 =0). How can I fix this? Here’s my code:

var obj = {
  a: 2,
  b: 3,
  c: 4
};

function removeEvenValues(obj) {
  for (var currentValue in obj) {
    if (obj[currentValue] % 2 = 0) {
      delete obj[currentValue]
    } else {
      obj[currentValue]
    }
  }
}
removeEvenValues(obj);
console.log(obj); // --> { b: 3 }

This line is using = instead of ===. A single = is assignment instead of comparison (===).

Yup, that’s it. Thanks!
