Code Blocks

Basic Code Block

Add a language identifier after the opening fence for syntax highlighting:

const greet = (name: string) => "Hello, " + name;
console.log(greet("World"));

Add title="..." to show a filename above the block:

lib/utils.ts

export function cn(...classes: string[]) {
  return classes.filter(Boolean).join(" ");
}

Add {n} or {n-m} to highlight specific lines:

function add(a: number, b: number) {
  // highlighted line
  return a + b;
  // also highlighted
  // also highlighted
}

function greet(name: string): string {
  return "Hello, " + name;
}

function greet(name) {
  return "Hello, " + name;
}

def greet(name: str) -> str:
    return "Hello, " + name
