In a class, we should instead name this.setState() to revise the amount condition:

In a purpose, we currently have setCount and matter as variables so we don’t need this :

We’re calling our very own varying matter given that it retains the sheer number of key presses. We initialize they to zero by-passing 0 because only useState debate. The 2nd returned item try alone a function. It lets us upgrade the count so we’ll label they setCount .
