How to use window.setinterval function

window.setInterval function is a method in JavaScript, used to execute specified functions regularly. This function will be executed repeatedly according to the specified time interval until the clearInterval method is used to stop execution.

The syntax of the window.setInterval function is as follows:

window.setInterval(function, milliseconds, arg1, arg2, ...)

Where "function" is the function to be executed or the code block to be executed.

"milliseconds" is the time interval between function executions, in milliseconds.

"arg1, arg2, ..." are optional parameters used to pass to the executed function.

The following is an example showing how to use the window.setInterval function:

javascript let count = 0; function increment() { count++; console.log(count); } let intervalID = window.setInterval(increment, 1000);

In the above example, we define a function named increment that will count every time it is called. Increase 1 and print out the value of count. Then, we use the window.setInterval function to execute the increment function every second. Every second, the increment function is called once, and the value of count is incremented and printed on the console.

If we want to stop scheduled execution, we can use the window.clearInterval method and pass it the return value of the setInterval function:

javascript window.clearInterval(intervalID);

In the above code, we use window.clearInterval to stop it The scheduled execution represented by the previously created intervalID.

To summarize, the window.setInterval function is a method in JavaScript that is used to repeatedly execute a specified function at a scheduled time. It can be used in front-end development to implement functions such as animation effects and periodic sending of requests. Use window.clearInterval to stop scheduled execution.
