[Solved] How to stop setInterval method inside of a function

Question

https://code.sololearn.com/WxlP08iSoXs2/?ref=app

Hello, I can't stop a setInterval that I called using a function, how to stop this?

const laugh = () => {
setInterval(() => {
console.log("haha");
},5000)
}

laugh();

setTimeout(() => {clearInterval(laugh);},10000)

I also tried making a parameter on laugh() but things gets worst.
ClearInterval(laugh(stop));

stop is a parameter inside of laugh() and I assigned setInterval to that stop, so I assumed ClearInterval(laugh(stop)); will make it stop, but what happen is, it creates another setInterval which make it more frequently laughing 😂, this one is laughing non-stop, please, I'm pissed 😡 (JOKE), early thanks for helping.

Answer 1

clearInterval() uses the ID that was returned by setInterval(). So you need to have that ID stored somewhere (in a variable), that can be accessed when we want to stop the interval.

let timerID = null;
const laugh = () =>
{
timerID = setInterval( () =>
{
console.log( "I'm unstoppable'" );
}, 1000 );
}
laugh();

setTimeout( () =>
{
clearInterval( timerID );
console.log( "Yeah right ..." );
}, 10000 );
