What are parameters and arguments in JavaScript?

Can you explain what parameters and arguments are in JavaScript?

Sure! In JavaScript, parameters are the names listed in a function's definition, while arguments are the actual values passed to the function when it is called.

Can you give me an example of a function with parameters and how to call it with arguments?

Absolutely! Here's a simple example:

function greet(name) {
    return `Hello, ${name}!`;
}

console.log(greet('Alice')); // Output: Hello, Alice!

In this case, name is the parameter, and 'Alice' is the argument.

What happens if I don't pass an argument to a function?

If you don't pass an argument, the parameter will be undefined inside the function. For example, greet() would return 'Hello, undefined!'

Are there any differences between parameters and arguments in other programming languages?

The concepts are generally similar across languages, but the syntax and behavior can vary. For instance, some languages allow default parameters.
