Thanks 🙏🏻

This is a criminally underrated channel. There aren’t much resources for FE engineering like BE engineering.

Very good stuff. in clearInterval Poly shouldn't it be clearTimeoutPoly(intervalMap[id]) ?

[@aliasgartaksali7785]

yes, it worked because both id's were same, if we generated random number then it will break

[@rupeshsharma3754]

How can we create polyfill of "new" keyword in Javascript? If possible could you please make video on this?

[@aniketpadmansh4213]

This is some great stuff... 😁🔥

[@js_cafe]

Thanks ❤️

[@aadarshverma9925]

At line 23, it should be clearTimeoutPoly(intervalMap[id]) instead of clearTimeoutPoly(id)?

[@saharshjain922]

I also think so

Im getting a "requestIdleCallback is not defined" error. Coul not find solution anywhere

[@AmanAnand-ym8wv]

I think we don't need a setTimeout. we can create and update the start Time as we did before in setTimeout but not delete the timerId once time is elapsed
function createTimeInterval(){
let intervalId = 1;
let storedIntervals = {};
function myInterval(callback,delay,...args){
let id = intervalId++;
let start = Date.now();
storedIntervals[id] = true;
function recur(){
if(!storedIntervals[id]) return;
if(Date.now() > start+delay){
callback.apply(this,...args);
start = Date.now();
}
requestIdleCallback(recur);
}
requestIdleCallback(recur);
return id;
}
function myclearInterval(id){
if(storedIntervals[id]){
delete storedIntervals[id];
}
}
return {myInterval, myclearInterval};
}
Please let me know if this is wrong

This should actually work and in my opinion a cleaner solution.
