The Marble Diagram—Our Secret Weapon
Explore the fundamentals of marble diagrams as a visual tool to understand the execution of RxJS operators in Angular. Learn to read the timeline, values, completion, and error statuses within observables to better comprehend asynchronous data streams and operator behavior.
We'll cover the following...
Now that we’ve learned about the advantages of using RxJS in Angular and how it makes dealing with some concepts smoother, let’s explore the marble diagram, which is very handy for understanding and visualizing the observable execution.
RxJS ships with more than 100 operators. Operators are one of the building blocks of RxJS. They are very useful for manipulating streams. All the reactive patterns discussed in this course are based on operators. And when it comes to explaining operators, it’s better to refer to a visual representation. And that’s why there are marble diagrams, thankfully! ...
