I have one suggestion: Please review the first code example provided in the PR file. I have attached a screenshot of my CLI showing the output, and I have also written the output in the shell. You can choose whichever approach you prefer, and we can proceed with that, deleting the alternative entry.

Hi @dakshdeepHERE! :) I gave some feedback on your article. Looks pretty good so far! :) (Note: I'm not a maintainer. Just a friendly contributor who wanted to help you. 😄).

Hey @CBID2 I never knew we were allowed to review others code and suggest changes. This is a good practice imo to help maintainers. Maybe I would do some code reviews too if they are from my tech stack from next time.

CBID2 · 2023-06-14T02:43:13Z

Oh of course we can @dakshdeepHERE! It's a common practice in open source! :) I wrote a FreecodeCamp article on how to review people's code. Check it out! 😊

dakshdeepHERE · 2023-06-14T04:41:39Z

@CBID2 yes I do that in other repo owned by my friend but I thought it's against the TOS here.

Hey @yangc95 I have few more optional codes that I wanted to add but I didn't as the article already is above 300 lines. If you want I can add them. But I think the code samples of creating threads for the functions and message between threads are enough for basic understanding of threads.

@dakshdeepHERE Thanks for your patience!

I conducted a review and left comments. Please let me know if you need anything clarified! In addition. The comments are a bit open-ended due to the nature of a tutorial article which you'll notice.

Let me know once you've addressed any requested changes 🙂

Could we place links here, it should look like:

+A `thread` is a path of execution within a process, which can contain multiple threads. It is also known as a lightweight process. The goal of threading is to achieve parallelism by dividing a process
+into multiple threads. For example, in a browser, multiple tabs can be different threads. MS Word uses multiple threads: one to format the text and another to process inputs, etc.

MS Word uses multiple threads; one thread may format the text while another another processes inputs.

Elegant definition! Could we also include a short definition on processes here? Also, what about concurrency v parallelism

Also, make sure to place focus on what this tutorial will accomplish in the intro

Can we swap out S.N for something more meaningful or remove it

Would work well as a numbered list

It'd also be good to have a short explanation on what each is

Haha I'm so used to this listing that I've literally stopped using the numbered list

Got it

+## Multithreading

+- A `thread` is a path which is followed during a program’s execution.


This would be good for Docs formatting. As this is an article, can we use paragraph format unless we're creating some itemized list or specifically listing out parts of some kind

+- `Data dependency` – sometimes the data required by one thread (T1) might be produced by another (T2). Thus, T1 can not run before T2. Therefore, it becomes difficult for programmers to code.
+- `Testing and debugging` – Multiple threads running in parallel on multiple cores poses another challenge in the testing of applications.

@yangc95 Thank you for the amazing review I will get started with the changes. I'm totally blown away by the range of your knowledge in computer science after reading your comments in this entry. Devs like you always motivate me. Thanks for the correction.

@dakshdeepHERE Hiya! Just pinging you on this as a light reminder 🙂 hope your studies are going along!
