What is the difference between function expressions and function declarations?
An example of an AI chatbot conversation about function expressions and declarations in JavaScript.
What is the difference between function expressions and function declarations?
Function declarations are hoisted and can be called before they appear in the code, while function expressions are not hoisted.
Can you give me an example of each?
Sure! A function declaration looks like this: function myFunc() {}. A function expression would be: const myFunc = function() {}.
Are there any advantages to using one over the other?
Yes, function declarations are easier to read and understand, while function expressions can be more flexible, especially with anonymous functions.
What about arrow functions? How do they fit in?
Arrow functions are a type of function expression that provide a shorter syntax and do not have their own this context.
