How JavaScript is passed to setInterval () and setTimeout () using functions instead of strings

This article mainly introduces how JavaScript is passed to setInterval () and setTimeout () using a function instead of a string, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

Use functions instead of strings when passing to setInterval () and setTimeout ()

If you pass setTimeout () and setInterval () a string, they will convert it in a way similar to eval, which will certainly be slower, so don't use:

SetInterval ('doSomethingPeriodically ()', 1000); setTimeout ('doSomethingAfterFiveSeconds ()', 5000)

Instead, use:

SetInterval (doSomethingPeriodically, 1000); setTimeout (doSomethingAfterFiveSeconds, 5000); Thank you for reading this article carefully.
