30 second in javascript

You can use setTimeout() function to delay a piece of code to execute by a specified number of milliseconds. To wait 30 seconds, you can use like this:

index.tsx
setTimeout(function() {
  // code to be executed after 30 seconds
}, 30000); // 30,000 milliseconds = 30 seconds
113 chars
4 lines

If you want to execute a piece of code repeatedly after a certain number of seconds, you can use setInterval() function.

index.tsx
setInterval(function() {
  // code to be executed every 30 seconds
}, 30000); // 30,000 milliseconds = 30 seconds
114 chars
4 lines

Note: setTimeout() and setInterval() are asynchronous functions, so the actual delay time may not be precisely 30 seconds, especially if your code is heavy or the browser is busy with other tasks.
