By the end of this tutorial, you should be able to handle setTimeout like a pro!
How setTimeout works
Most of us use setTimeout all the time without realizing it.
It's a handy function that helps us control the code execution after a set delay.
The code will run once after the specified delay has passed when using it.
You can specify a delay in milliseconds, which allows you to precisely control how long the code will wait before executing the code inside.
For example, you can use it to queue up multiple tasks and run them all at once after the delay has elapsed.
Passing Parameters to setTimeout
It takes two parameters: the function name and the delay value in milliseconds.
You can also pass the direct callback or an arrow function as the first parameter.
Let's take a look at an example of how to use it.
Redirect a user to a different page after 5 seconds.
clearTimeout – Clear the execution of setTimeout
Clearing the timeout period is useful for a variety of purposes in code.
It can be used for cleaning up code or canceling an action that was already started.
For example, if you set a timer for 10 minutes and want to cancel it early or cancel the timeout based on a specific condition. You can use clearTimeout.
This will stop the timer from executing and return the timer to its initial state.
You can also use clearTimeout to avoid infinite loops and other problems.
