How do arrow functions differ from regular functions?

Arrow functions are a shorter way to write functions in JavaScript, but they behave differently from regular functions.

Key Differences:

1. No this binding
   Arrow functions do not have their own this.
   They use the this value from their surrounding scope.
   Regular functions have their own this.
2. Shorter syntax
   Arrow functions are more concise.
3. Cannot be used as constructors
   You cannot use new with arrow functions.
4. No arguments object
   Arrow functions don’t have their own arguments.
   Regular functions do.
5. No prototype
   Arrow functions do not have a prototype property.
