RxJs: Beginning
RxJs is one of the vast topics in itself that we can write a complete article about. I have seen and read many articles with some important and limited topics with some code snippets but couldn’t find one such piece with a complete brief about it. So, here we go for something different. Here we go:: => The term RxJs stands for Reactive Extensions For Javascript. It allows us to work with an asynchronous data stream. It provides one core type: I.e., Observable, and the other three types are Observer, Schedular and Subject. Observables and Observers in RxJs So, we use Observables to perform asynchronous operations and handle asynchronous data. We can manage asynchronous operations in Angular using either Promises or Observables. Now, what are asynchronous operations and asynchronous data? We already know that JavaScript is a single-threaded programming language, meaning the code is executed line by line. Once one code is complete, only the next code in the program will be e...
