title: How do i find the numbers that is not followed by a word character with regex?
body: <p>I'm trying to do this thing that searches the number that is <strong>not</strong> followed by an &quot;i&quot;, for example:</p>
  <p><em>21i</em> and <em>16</em>, it should only match 16</p>
  <p>I tried <code>/\d+(?!i)/</code> but it also matches the <em>2</em> in <em>21i</em>, how do i fix it?</p>
