Welcome to the book “Angular Observables and Promises: A Practical Guide to Asynchronous Programming”. In this book, I explain how to use observables and promises effectively for asynchronous programming. I show you practical scenarios and explain when you should use them and which operators you need to use. I will give you best practices with important pointers that, when used correctly, can make all the difference and have a big impact on performance. There are also things you should be aware of and avoid when working with observables, otherwise performance can be affected. By the end of this book, you will be able to use Observables and Promises in your Angular application and handle all kinds of scenarios. Let us get started.

Unidades Físicas, Dimensiones y Observables

¿Qué son las unidades y las dimensiones físicas? No es trivial esclarecer “qué es (en esencia) una dimensión física“. Lo que si podemos hacer es decir que la física trata de magnitudes susceptibles de ser medidas, y que cada magnitud física se clasifica según su dimensión y se miden a través de comparaciones con una unidad. Existen dos tipos de unidades físicas: las fundamentales y las derivadas…

Learn About Observables, Observers And Operators of RxJS – Angular

In this blog, we will learn about some basics of RxJS and its components like Observables, Observers and Operators. So, first of all, what is RxJS?

RxJS (Reactive Extensions For JavaScript) is a library for reactive programming using observables that makes it easier to compose asynchronous or callback- based code (RxJS Docs).

In the above definition of RxJS, you have encountered the word r…
