- Learn how to create an object method
- Learn about the concept of this, and how does this relate to objects.
- Learn what happens when an arrow function is used as an object method
Before going further, what is this? This has different meanings depending on execution context. For example, the Windows object when working with a browser. In this case, this references the object where the function resides. This.userName refers to the current userName value inside of this object.
Now, below the object, I will type user.userInfo, and because this is a function that I wish to execute, I need to add parentheses. I will execute this and on the right, there is the userName and email. Now, one caveat about creating object methods. You should not use an arrow function to create one. I will demonstrate why. I'm gonna convert this function to an arrow function. I will execute the method again and in the console, there are two undefined values.
