      @Akshay Saini Debouncing will be suited for shooter games because user can stop shooting at any time, regardless of interval you have set and he can fire at any time so.. we should allow player to fire shot at any time unlike throttling fixed synchronous intervals shots will be delayed if your fire is not in sync with throttle intervals. My implementation would be the inverse of debouncing like count time in ms after any shot and then allow next shot after 200 ms for a pistol, i.e. block for 200ms whenever fired!!

    • @robinsoni4778

      Hi @Akshay Saini,
      The Right words to explain this would be - Debouncing: Needed when we want to run the function after the user has stopped interacting for at least given limit time,
      Throttling: When requirement demands to run the function with the gap of limit time b/w two consecutive function call while user's interaction.
      I have deduced it after checking your code for both debouncing and throttling, please let me know if my interpretation is wrong. Thanks for the nice explanation.

    Throttling:
    Baby: Mom give me a piece of chocolate cake
    Mom: No you can get one, only after 1 hour
    (baby wont get a piece of cake no matter how many times she asked, but only after each hour)
    Debouncing:
    Baby: Mom give me a piece of chocolate cake, . . .Mom give me a piece of chocolate cake ... mom give me ...
    Mom: No, You will get a piece of cake only after 1 hour from LAST time you asked for one. 😃

    Well I am quite new to webdev, just 2-3 months still learning things. I still remember when I was thinking how to verify username is valid or not the first thing that came up to my mind was it would take so many API calls and is not efficient. Then I dropped the idea of implementing it but this video makes such a great sense.
    I had not heard of this term before and didn't had idea about it. I just saw it and thought here is something new to learn.
    You solved my problem in such an easy way.
    Thank You!

    from JS engine's perspective
    throttling: I am working on something which might take x milliseconds, so don't disturb me for next x milliseconds
    debouncing: first you finish your action (typing, clicking) & then after x milliseconds I will fetch the required data

    A debounced function may starve but a throttled function would never.

    • @VijayKumar-zx5bm
      @VijayKumar-zx5bm Pƙed 5 lety +21

      +one more to add. Sometimes in throttling, the final function call may not be happen whereas it would happen for debouncing.
      Eg Consider the situation of search bar, where on typing a key an API call is fired . Let the duration for throttling / debouncing be 3sec and say we are just searching string AI . In this case if the second key press (which in our case is key I ) is within 3 sec, then the search event won't be fired in Throttling whereas in Deboucing the search will be fired after 3 sec with AI as the string in the API call .

    In simple terms:
    Debouncing delays the execution of a function until there's a pause, typically after a certain period of inactivity.
    Throttling limits the rate at which a function can be called, ensuring it's not executed too frequently.

    Visualizing the Difference
    Throttling: Imagine you are trying to listen to someone talk in a noisy room. You decide to check for new sounds only every 200 milliseconds. You might miss some details, but you get a general idea without being overwhelmed.
    Debouncing: Imagine waiting for a pause in the conversation to respond. You will only start talking after the person has been silent for 200 milliseconds, ensuring you don't interrupt them and respond only when they are finished.

    In the interview process for Frontend Engineers (FEE2 at Amazon in particular), is the system design part of the interview the same as the system design for WDE2/SDE2 roles? As in, since FE engineers are confined to the frontend, will the system design be related to frontend itself (scaling frontend, design systems, etc) OR will it be along the line of designing Dropbox or URL shortener, etc.?

    Debouncing and throttling in one line.
    Debouncing - Only call the function when the difference between the last and current events exceeds the limit.
    Throttling - Only call the function when the difference between the last and current functions exceeds the limit.
