Build an Emoji Reactor - Step 15

JavaScript

Tell us what’s happening:

I found a bug :slight_smile: this passes the test:

btns.forEach(b => b.addEventListener(‘click’, (btn) => updateCount(btn)))

“btn” is not a button, it is an event, but the updateCount() is waiting for the target object.

Your code so far
