Hey @disha-1302! Saw your work on GSSoC 2026.

We are building TermUI, a TypeScript terminal UI framework with React-style hooks and JSX, rendered entirely in the terminal.

We have 67 unassigned GSSoC issues open. 19 are marked good first issue. Your JavaScript background transfers directly.

Hi @Karanjot786 ,

Thanks for reaching out! TermUI sounds interesting, especially the React-style hooks and JSX approach in the terminal.

I'm participating in GSSoC 2026 and would like to explore the project. I'll go through the open issues and see where I can contribute.

Thanks for the invitation!
