Katex is a fast & lightweight math typesetting library. In this website you can test katex outputs. You can copy, copy with \ instead of \ (for those programming language where \ is printed out by \) and reset. You will have an overview of Katex. I used Svelte for this project, Svelte is so fast 🦾🦾
