In JavaScript, you can compare if two values are equal using the identity operator, which is also called strict equality. For example, in the following code, you’re comparing value a with b:

a === b; // strict equality or indentity operator

Interceptors are code blocks that you can use to preprocess or post-process HTTP calls, helping with global error handling, authentication, logging, and more. In this article, you’ll learn how to intercept JavaScript Fetch API calls.

A changelog is a detailed record of any changes you’ve made to your project over a period of time. Not only does a changelog serve as a starting point for fixing bugs and errors, but it is also a valuable educational resource when introducing new developers to your project.

TL;DR: In this post, we will look at prototypes and how to use them for inheritance in JavaScript. We will also see how the prototypical approach is different from class-based inheritance.

TL;DR: In this article, you will learn how to develop an audio player app using Angular and RxJS. You will handle audio operations and application state using RxJS. To secure your application, you will use Auth0. If needed, you can find the final code in this GitHub repository.

TL;DR: In this article, we will reverse engineer Observable from the RxJS library. We will also re-create a couple of operators from the library and learn about Observer and Subscription. We are also going to use TypeScript to annotate the code. In the end, we will write a very small example code to use that reverse engineered library. You can find the demo at StackBlitz.

TL;DR: In this article, you will learn about what's new in Ionic 4, changes in the existing features, how to migrate your Ionic 3 app to the Ionic 4 app, and about using Ionic with Stencil and Capacitor. Finally, you will create a simple application using Ionic 4 to see the new version of this framework in action. If you need, you can check the final code of the app that you will create on this GitHub repository.

TL;DR: In this article, you will learn how to develop a mobile audio player app using Ionic framework and Angular. You will handle audio operations using RxJS and Observables, and you will also explore how you can manage application's state with NgRx. To secure your application, you will use Auth0. If needed, you can find the final code on this GitHub repository.
