When should I use regular functions in JavaScript?

Regular functions in JavaScript are best used when you need a function that is not bound to a specific context, or when you want to define a function that can be called in various scopes.

Can you give me an example of a regular function?

Sure! Here's a simple example:

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

You can call this function with any name, and it will return a greeting.

What about arrow functions? When should I use them instead?

Arrow functions are great for shorter syntax and when you want to preserve the this context from the surrounding code. Use them when you need a concise function expression.

Are there any performance differences between regular and arrow functions?

In most cases, the performance difference is negligible. However, regular functions can be slightly faster in some scenarios due to their simpler structure.
