When we have setted a timeout, it lasts one time and after it doesn't make part of our program.

Am I right?

Hello Vic,

Are you referring to the setTimeout() function? If so, you are correct. The setTimeout function takes one callback (a function as a parameter), and then specific amount of time before that callback/function is ran. And it's ran only once.

For example: 

function displayHelloText() {
   console.log("Hello!");
}

setTimeout(displayHelloText, 3000);

displayHelloText would run one time after three seconds passed.

If you'd like for your function to run more than once, you can use the setInterval() function.

Hope that helps! And if you're asking about something completely different, just let me/us know.

Here's a great Treehouse course from Chalkers on how to use setTimeout() and JavaScript callback functions.

Why are you using setTimeout instead of window. ...
