Javascript Programming Tutorials, Guides & Best Practices

• Quick Testing: Test snippets of JavaScript code without setting up a development environment.
• Debugging: Check errors and log values during code execution.
• Real-Time Interaction: Manipulate and inspect web page elements dynamically.

• Open the browser.
• Right-click on the webpage and select Inspect or press Ctrl+Shift+I (Cmd+Option+I on macOS).
• Go to the Console tab.

console.info('This is an info message');  // Output: Info: This is an info message
console.warn('This is a warning message');  // Output: Warning: This is a warning message
console.error('This is an error message');  // Output: Error: This is an error message

You can override console.log to add custom behavior, such as logging to a file, sending logs to a server, or adding timestamps.
