What is the difference between function declarations and function expressions in JavaScript?
An example of an AI chatbot conversation about JavaScript function declarations and expressions.
What is the difference between function declarations and function expressions in JavaScript?
Function declarations are hoisted and can be called before they are defined, 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 great for defining functions that need to be available throughout the scope, while expressions can be useful for creating anonymous functions or when you want to pass functions as arguments.
