What are arrow functions in JavaScript and how do they handle parameters?
An example of an AI chatbot conversation about arrow functions and their parameter handling in JavaScript.
What are arrow functions in JavaScript?
Arrow functions are a concise way to write function expressions in JavaScript, using the '=>' syntax.
How do they handle parameters?
Arrow functions can take parameters just like regular functions. You can define them in parentheses before the arrow.
Can you give me an example?
Sure! Here's an example: const add = (a, b) => a + b; This function takes two parameters and returns their sum.
What about when there’s only one parameter?
If there's only one parameter, you can omit the parentheses: const square = x => x * x; This squares the input.
