Learning RxJS Operators by Example Playbook from Pluralsight

The strength of RxJS is its over 100 operators; they provide the power. Learning those operators was hard, until now. This course will teach you every single operator, with examples and marble diagrams, all in framework-agnostic vanilla JavaScript.

The true strength of RxJS is the over 100 operators it includes. Unfortunately, this is also a weakness - it's hard to learn everything those operators offer. In this course, Learning RxJS Operators by Example Playbook, you will learn how the power these operators offer can make your applications easier to code and troubleshoot. First, you will explore how to improve performance. Next, you will discover operators that you didn't even know existed. Finally, you will be able to add them to your coding toolbelt. Every single operator is covered; first in an overview with a marble diagram and then in code, with at least one example per operator. All examples are in vanilla JavaScript so there's nothing extraneous. Watch it straight through to learn it all, or jump in and skip around to learn just the operators you need right now. When you're finished with this course, you will have the skills and knowledge of RxJS needed to write high-performing, easy-to-maintain code.
