Object Oriented JavaScript Tutorial #7 - Method Chaining

Показать описание

Hey gang, in this Object Oriented JavaScript tutorial I'll explain what method chaining is, and how we can set this up to work by editing the return value of the methods inside our User class.

For those who are learning about method chaining for the first time: the UpdateScore function is not necessary to method chain userOne.login().logout() or any other variant. All you needed to add to your code (assuming you have the same code as the last video) is "return this;" under the two functions "login" and "logout" . Shaun simply added the function updateScore because he wanted to arbitrarily count starting from 0 each time the updateScore function is called. Hope that clears the air for any that are confused!

This series (past few videos) is the most excellent explanation of classes i've seen. And i've searched for good explanations a lot the last few days. So: a very big thank you!

Wow, I've been using method chaining this whole time and didn't realize how easy it is to implement yourself. Thanks for the great explanation!

Thanks. Learnt something new today coming from a Java backround. I did encounter this type of method usage a lot with the Java 8 Streams API but I never new how it was implemented and what it was called. This also made the Builder Pattern i was reading about ages ago make a lot more sense! Awesome video overall. Cheers.

Thanks for the clear explanation. It took me a few minutes to realise what's happening. I was using -> let newUser, instead of -> var newUser. And it wasn't obviously working because of scope.
