One of the big challenges of learning Angular is RxJS. Rupesh will explain what you will learn in this course.

In order to get most out of this course. I will recommend, to have some basic knowledge on RxJS observables and RxJS basic operators. You do not need expertise on them, just basic understanding is enough to start with this course. Also, Feel free to watch my Free RxJS courses for beginners and advanced level in Fullstack Master.

Rupesh will explain what are the topics you will learn in this section. Like Higher order Observables, Higher order observable Mappings and working on Angular projects to use higher order operators.  

Rupesh will explain why you should learn higher-order RxJS Observables. Especially if you are looking forward to working on NgRx Angular project or If you are preparing for an interview then you must watch this course. 

Rupesh will give you the github url to get the coding exercise source code for this entire course. Source code is attached to the first module feel free to download them. 

Rupesh will explain how to download source code and will walkthrough the source code and guidelines.

Rupesh will walk you through the demo application source code and he will explain how to install its dependencies.

Rupesh will start the demo application and show you its features like search order, submit order, delete order etc.

What will you learn in the First order observable section?

Learn what exactly is observable and how it behaves.

Learn what exactly is First-Order Observable and learn one example.

Rupesh will give a definition of first order RxJS observable mapping operator and explain by one example.

Rupesh will ask you to write code to add cart item total property to a given cart item observable and give you a solution as well.

Rupesh will ask you to write code to take cart items and return cart total count observable and give you a solution as well.

Rupesh will summarise the First-Order Observable section.

What will you learn in the Higher-Order observable section?

Rupesh will explain what is Higher-Order observable?

Rupesh will explain why you should learn Higher-Order observables by giving one real world scenario where you want to fetch an order detail from a server.

Rupesh will explain how to identify higher order observable by explaining you inner and outer observable by giving one real world example.

Rupesh will explain how developers fall in the trap of nested subscription anti-pattern rather than using higher-order operators.

Rupesh will give you a challenge to solve fetch orders from a server problem using a first order operator and ask you what did you learn?  In Next video you will see the solution from Rupesh.

Rupesh will ask you to solve the fetch order problem using a first order mapping operator. Rupesh will also give a solution to the challenge in this video. You will learn to identify nested-subscription.

What will you learn in the Higher Order Mapping section?

Rupesh will explain what higher order mapping means? 

Rupesh will explain what a nested subscription is and why it happens?

Rupesh will explain what are the problems you will face if you use nested subscriptions in your project. 

Rupesh will tell you what are the 4 major higher order mapping operators. 

Rupesh will give you a trick to identify the higher order mapping operators.

Rupesh will discuss the benefits of Higher order mapping operators.

Rupesh will discuss the problem of nested subscriptions and give you hints on how we can solve this using higher-order operators.

Rupesh will discuss the solution of fetch order from the server using switch map higher order mapping operator.

Rupesh will summarize the Higher-Order Mapping operator section.

Rupesh will explain what you will learn in the Important Higher Order Mapping Operators section.
