Markdown and LaTeX

Everything fundamental renders out of the box — including typeset math. This note is the living cheatsheet.

Text

Bold, italic, strikethrough, and inline code. A link too. Use a hard break by ending a line with two spaces, or just let paragraphs flow.

Lists

1. Ordered item
2. Second item
   • Nested bullet
   • Another
3. Done

And task lists:

• Render markdown
• Render LaTeX
• Add a note about the thing

Blockquote

Stay curious. The notes you keep today are the memory you’ll want tomorrow.

Code

Inline const x = 1;. Fenced with a language tag:

// A tiny debouncefunction debounce(fn, ms = 200) {  let t;  return (...args) => {    clearTimeout(t);    t = setTimeout(() => fn(...args), ms);  };}

def fib(n):    a, b = 0, 1    for _ in range(n):        a, b = b, a + b    return a

Table

LaTeX

Inline math: the quadratic formula $x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a}$, and the golden ratio $\varphi = \frac{1 + \sqrt{5}}{2}$.
