Finally I understood clearly, what is the difference between debounce and throttle. Thank you. This is the best channel for UI guys.

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); } }; }

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

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

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

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 жыл бұрын

that works too man. I do that sometimes as well

@Cognitoman 2 жыл бұрын

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

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

@ankursehdev1583 4 жыл бұрын

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]
