Markdown Editor

A full-featured editor with live preview, Mermaid diagrams, math, and syntax highlighting.

---

Formatting

Bold, italic, strikethrough, inline code.

Blockquotes look clean too.

Code

// Fibonacci with generators
function* fib() {
  let [a, b] = [0, 1];
  while (true) { yield a; [a, b] = [b, a + b]; }
}
const first10 = [...Array(10)].map((_, i) => {
  const gen = fib();
  return [...Array(i + 1)].reduce((_, v) => gen.next().value, 0);
});
