Understanding how to use console.log() is a fundamental skill for debugging JavaScript code. This tutorial covers printing messages, displaying variables, and using multiple arguments in console.log() to help you quickly inspect and troubleshoot your code.

Code

// Print a simple message to the console
console.log("Hello, World!");

// Declare a variable and print it with a greeting
const name = "Alice";
console.log("Hello, " + name);

// Print multiple values and their types in one line
console.log("Value:", 42, "Type:", typeof 42);

Key Points

• console.log() prints messages and variables to the browser console for debugging.
• You can concatenate strings and variables using the + operator inside console.log().
• Multiple arguments separated by commas can be passed to console.log() to print values and labels together.
• Using typeof inside console.log() helps quickly check variable types during debugging.
• Regularly using console.log() makes it easier to understand code flow and find errors early.
