Hi Akshay,
Because of your true efforts to learn and let others learn, i today got selected in amazon. Thanks a lot 🙏

[rajraju]

Very good explanation @Akshay. However there are few bugs and unused variables in the code.
1. You haven't used 'fn' param in debounce function, though you have passed the 'argument' - 'getData' from 20th line.
2. If you had used the 'fn' param in the setTimout function, you would have avoided the getData function in line no.15
3. If you had adjusted the 2nd point right, you wouldn't need to keep the reference of 'this' and 'arg' unnecessarily, It would have automatically keeps the outer function params value intact. ( That's what closure does).

Hi brother I am watching your videos for some time now and in intial period I thought this is going to be like other channels with few tutorials of this and then few tutorials of that but I was wrong this is purely javascript based 100% pure content, I am Software Engineer in test at EA sports I can say the info you provide is legit, I use javascript everyday and use atleast 60% to 70% concepts you covered. Keep on doing this, we need more content creators like you. Stay motivated stay hungry
