Migrate codebase to Typescript

[rickstaa]

Is your feature request related to a problem? Please describe.

We currently use javascript + type definitions. I, however, think migrating the project to typescript will significantly improve the development experience since it allows us to catch errors earlier.

Extra information

There were some attempts in the past that people can build upon if they want to take on this issue:

• Refactor project with TypeScript and JSX & Support LeetCode Card #1288
• Typescript #832

Additionally, @HwangTaehyun translated part of the codebase to typescript when creating https://github.com/HwangTaehyun/github-contributor-stats.

Hi @rickstaa,

I would like to work on this issue if that's okay with you as part of hacktoberfest.

[rickstaa]

@Guri-X First of all, welcome to the community! 🚀 Amazing that you decided to choose to improve GRS as part of https://hacktoberfest.com. Both me and, to my knowledge also, @anuraghazra are big fans of typescript, so having this repository in typescript would be amazing! I assigned you to the issue.Feel free to tag me if you have any questions.

[rickstaa]

Let me know if the hacktoberfest proposal is accepted. Other candidates would be #1761 or #2053. For the last one, you could ask to team up with @Pranav2612000.

Thanks @rickstaa for the references. I'll update here as soon as I made some progress.

@Guri-X @rickstaa Can I participate too? I also really like typescript and I am very interested in it! Also, since I've worked here once, I think it might be helpful.

[guriWiz]

Of course @HwangTaehyun, everyone is welcomed to join. I'm currently a beginner when it comes to typescript so I think i'll get to learn a lot from you.

Let's TypeScript this bad boy.

The typescript master has spoken! Let's do this 🚀.

@Guri-X, @HwangTaehyun please check #2076 for GRS-related information about this year's Hacktoberfest. I just signed up as a maintainer and read the guidelines. For your contributions to be valid Hacktoberfest PRs, you must create separate PRs. Therefore, I think it is best that one of you performs the initial typescript setup (see https://webpack.js.org/guides/typescript/) and shares that commit with the other. After that, you can divide folders or files to work on. Feel free to let us know if you have any questions or run into problems 🤓.

@HwangTaehyun, I know you already migrated part of the code to typescript in https://github.com/HwangTaehyun/github-contributor-stats. Maybe you can set up the initial typescript template and add the types you already have, after which you can divide the remaining files?

Happy hacking! 🚀
