SetTimeout and scheduling function calls

Question

Given the following code, when will the go function be executed?

 setTimeout(go, 0); 

Will it be added to the end of the job queue immediately or added to the end of the job queue after the minimum interval for setTimeout ?

Answer 1

In most browsers, the minimum delay time is 4 ms. You can use lower values ​​without errors, but when the script actually executes, the browser will overwrite the timeout value.
