setTimeout and setInterval have no precision to speak of, they just throw the task into the event loop of js, and it may be their turn to execute.
setTimeout (() = > {xxx}, 0); will only be executed for you as soon as possible, but cannot be guaranteed to be executed immediately
refer to
" event loop "
actual delay ratio Reason for setting the value longer
if you only talk about the precision of parameters, millisecond
refer to API document
