Code Syntax Highlighting

NextWiki supports syntax highlighting for various programming languages using code blocks.

JavaScript

import { useState, useEffect } from 'react';

function Timer() {
  const [seconds, setSeconds] = useState(0);

  useEffect(() => {
    const interval = setInterval(() => {
      setSeconds(seconds => seconds + 1);
    }, 1000);
    return () => clearInterval(interval);
  }, []);

  return (
    <div>
      Seconds: {seconds}
    </div>
  );
}

Python

import requests

def get_data(url):
    try:
        response = requests.get(url)
        response.raise_for_status()  # Raise an exception for bad status codes
        return response.json()
    except requests.exceptions.RequestException as e:
        print(f"Error fetching data: {e}")
        return None

# Example usage
api_url = "https://jsonplaceholder.typicode.com/todos/1"
data = get_data(api_url)
if data:
    print(data)
