🚀 Modern JavaScript Essentials: Mastering ES6, Async & APIs

Sharing this visual guide that breaks down some of the most powerful features in modern JavaScript — the tools that every developer should be comfortable with today.

Here’s what it covers:

🔹 Arrow Functions (ES6) • Cleaner syntax compared to traditional functions • Lexical this binding that prevents common context errors • Perfect for callbacks and array methods like map()

🔹 Promises • Handle asynchronous operations without messy nested callbacks • Three states: Pending, Fulfilled, Rejected • Resolution methods: .then(), .catch(), .finally()

🔹 Async/Await (ES8) • Write asynchronous code that reads like synchronous code • Automatically returns promises • Cleaner error handling using try/catch

🔹 Working with APIs (Fetch API) • Modern way to make network requests • Parse JSON easily with .json() • Handle GET and POST requests efficiently

Modern JavaScript is not just about syntax improvements — it’s about writing more readable, maintainable, and scalable code.

If you're building web apps, APIs, dashboards, or full-stack systems, mastering these concepts is essential.

Angular Observables and Promises: A Practical Guide to Asynchronous Programming

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.
