JS in SetInterval () and SetTimeout ()

SetInterval () method definition and usage

The SetInterval () method invokes a function or evaluates an expression according to the specified period (in milliseconds).

The SetInterval () method keeps calling functions until Clearinterval () is called or the window is closed. The ID value returned by SetInterval () can be used as a parameter to the Clearinterval () method.

Grammar

SetInterval (code,millisec[, "Lang"])

Parameters	Description
Code	Necessary. The function to invoke or the code string to execute.
Millisec	Have to. The time interval, in milliseconds, between periodically executing or calling code.

return value

A value that can be passed to Window.clearinterval () to suppress periodic execution of code.

SetTimeout () method definition and usage

The SetTimeout () method is used to call a function or evaluate an expression after a specified number of milliseconds.

Grammar

SetTimeout (CODE,MILLISEC)

Parameters	Description
Code	Necessary. The JavaScript code string to execute after the function to invoke.
Millisec	Necessary. The number of milliseconds to wait before executing the code.

Hints and Notes

Tip: SetTimeout () executes code only once. If you want to call more than once, use SetInterval () or let code itself call SetTimeout () again.
