title: Javascript - Find the sum of all the multiples of 3 or 5 below parameter
body: <p>I'm attempting to do what the title says however this code does not function. Can anyone give any tips on how to make this return correctly?</p>
  
  <pre><code>function multiples(number) {
    let sum = 0;
    for (let i = 0; i &lt;= number; i++) {
  
    if (i % 3 === 0 || i % 5 === 0) {
      sum += i;
        }
      }
    }
  </code></pre>
