useState Hook example in React 16.8
In the previous post we saw that the useState Hook is used to define state props in a function
component, in this post we shall see a small example on how the useState hook
works in action.
In this post we will create a function component and define a state prop count using the useState hook, we will attach a function setCount which will be used to change the value of the count prop. We will also attach the setCount function to the click event handler of a button, so that each time the button is clicked the setCount function will be called which will increase the value of the count state prop by 1.
