What is the difference between functions and methods in JavaScript?

What is the difference between functions and methods in JavaScript?

In JavaScript, a function is a standalone block of code designed to perform a specific task, while a method is a function that is associated with an object.

Can you give me an example of a function and a method?

Sure! A function can be defined like this: function greet() { return 'Hello!'; }. A method would look like this: const obj = { sayHello: function() { return 'Hello!'; } }; Here, sayHello is a method of the object obj.

Are there any differences in how they are called?

Yes! Functions are called by their name, like greet(), while methods are called on an object, like obj.sayHello().

What about the context of 'this' in functions and methods?

In functions, 'this' refers to the global object (or undefined in strict mode), while in methods, 'this' refers to the object that the method is called on.
