[enchancement] Clean and optimize codingsheets file

[RajMhatre20]

While developing a feature in CodingSheet.js, I noticed some unwanted functions and a significant amount of commented-out code. Additionally, I observed suboptimal performance in the React developer tools, with the page taking an unusual amount of time to load. I also noticed that many elements are being re-rendered unnecessarily. For example, when marking items as completed or for later use, it seems unnecessary for the header to re-render. Could we investigate and address these issues to optimize performance and code cleanliness?

Furthermore, on the current live website, the coding sheet doesn't seem to load data.

if you think this is a valid issue, can i work on this?

Hi, appreciate your keen observations and detailed feedback. Thanks for highlighting the API issue; it's in the process of being updated and should be back online within a couple of hours.

I appreciate the issue you've raised, and I'd like to include a few additional points to enhance coding-sheets further :

• [ ] The issue you are suggesting
• [ ] The topics filter is not working properly - work on the topics filter
• [ ] Can we make the clock feature a bit more attractive? (I would like to hear your suggestions)

Absolutely, @RajMhatre20! I appreciate the contributions you've made, and I'd be thrilled to have you work on this issue.

API is working fine now! @RajMhatre20

Ah, I'm not yet adept at UI, but since you're asking for my suggestion, I would propose hiding the timer that shows 0 seconds for each problem. Instead, display only those problems where the timer is activated. This would reduce the time needed to identify which problems have active timers (problems with time > 0). This is just a suggestion, and I can't be certain it's a better idea than the existing one.

Appreciate the recommendation; I'll make a note of it. @RajMhatre20

@RajMhatre20 were you able to figure out why filters are not working properly??

[RajMhatre20]

It seems to be working on my end. Could you provide the steps to recreate the problem?

Got it
