JavaScript is a powerful language known for its non-blocking nature, enabling developers to create efficient applications using callback patterns. However, choosing between named and anonymous functions can sometimes be confusing. This guide will help you understand their differences, advantages, and when to use each one effectively.

Named Functions

A named function declaration looks like this:

function greet(name) {
  console.log(`Hello, ${name}!`);
}
greet('John'); // Output: Hello, John!

In this example, greet is a named function that logs a personalized message. Here's why named functions are helpful:

• Readability: They improve readability since they have meaningful names associated with them.
• Debugging: When an error occurs within a named function, stack traces display more informative messages than those containing anonymous functions.

Anonymous Functions
