清除间隔（）； 给定 setInterval 的 ID 不起作用

Question

First off, I don't want the function to start running as soon as I open the file, secondly I can't stop the interval...

I've tried the setInterval(sing, 1000) and get a number 7 but I can't stop the code by doing clearInterval(7)

function sing() {
    console.log("twinke twinke...");
    console.log("adadasdsad...");
}

setInterval(sing, 1000);

Answer 1

The ID to stop the interval is the result of "setInterval". For example:

// starting setInterval
const id = setInterval(() => {
 // do something...
}, 1000);

// to stop the interval
clearInterval(id);
