Your solutions are always better than the rest. Everyone else tries to use popular examples that I didn't get earlier and thinking you'd get it with their won explanation. Using a different approach with this button allows me to see from a completely different perspective.

can also be done as: function throttle(fn, wait) { let timerId = null; return function() { if (timerId == null) { fn(); timerId = setTimeout(() => { timerId = null; }, wait); } }; }

@kkk24157 4 года назад

Good one. But can u plz describe more how the return function taking rest arguments(...) And how it's executing by click event listener. A console log example will be great to understand

@my_vk_vlogs 4 года назад

Hi Techsith, I got a clear understanding of both(Debounce, Throttling) concepts. Here is one small clarification if we are developing a real-time application we are going to use a "spinner" or "loader" concept, And using spinner we can avoid multiple API calls or Submissions. In this situation, it is necessary to implicate Debounce or Throttling instead of the spinner. Please clarify my doubt Thanks

@utsavsharma2979 3 года назад

Can't you use settimeout in throttling just as you did with in debounce. Because I think that would be much easier to implement and understand

@thankfulnes 4 года назад

Thanks! Debounce is better performance or same?

@Techsithtube 4 года назад

The difference is more about the experience than performance. Throttle and Debounce have different applications.

@VIVEKsingh-gk3et 2 года назад

Can you please make a video on event looping and if you have already made it, then please provide the link. Thank you:)

@GaneshKumar-fv2cg 4 года назад

Sir - May be a naive question. How the 'e' maps to the ...args inside the throttle function?

@ankursehdev1583 4 года назад

arguments is an Array-like object accessible inside functions that contains the values of the arguments passed to that function. If you're writing ES6 compatible code, then rest parameters should be preferred. function foo(...args) { console.log(args); } foo(1, 2, 3); // [1, 2, 3] It can be anything actually! function foo(...helllo) { console.log(helllo); } foo(1, 2, 3); // [1, 2, 3]

@avag001 4 года назад

a nice comment)

@DanielHarrisCodes 3 года назад

If I was posting some data to an API, what's the advantage to using throttling to prevent multiple clicks vs disabling the button and then re-enabling once I get the response back?

@Cognitoman 2 года назад

that works too man. I do that sometimes as well

@Cognitoman 2 года назад

but what if you get a response back really fast like 1-2 secs and they spam it to much, you might wanna limit it too 5 seconds or something

@sten6160 4 года назад

there is no need to `return` in the last line. just execute the fn

@TheGryphon14 4 года назад

We need to pass a callback to addEventListener. That's why the return is needed

@lutif1415 Год назад

you missed the event's in between those 5sec window. In your explanation you said if I click 5 times in say 3 sec, and throttle window is 3sec. My 5 events will be fired but once in 3 sec. While your implementation you are destroying in between events . So in above case, only one event will be fired instead 5
