Adding Delays in React

23k

Adding delays in React is a great way to help your app feel more responsive and smooth. Delays are helpful when you have a lot of state changes that need to be reflected in the UI. It can also help with animations and transition effects.

There are many ways to add delays in React. You can use setTimeout(), requestAnimationFrame(), setInterval(), and even create your own timer function.

The first is to use setTimeout in order to delay the rendering of a function for a certain amount of time. The second is to use setInterval in order to repeat the function again after a certain amount of time has passed. The third is to use requestAnimationFrame which will let you know when it’s time for your render function to be called and then call it at that moment.
