JavaScript is a fundamental asset for any web developer. As an evolving language, new releases continue to refine it to make it more accessible for large-scale use. ECMA Script, or ES in short, is the standardized name for the programming language popularly known as JavaScript. The sixth release of the script is known as ES6 and features major enhancements which improve Javascript's usability. Writing and reading code is now easier with the introduction of features like Arrows, Symbols, etc. 

This course provides a practical view into all of the components present in ES6. We'll discuss the importance of each component, learning how and why it makes things simpler in Javascript. Interactive exercises and quizzes will help you adopt these modern coding practices for JavaScript. ES6 is rapidly growing in popularity, and this course is essential for anyone who wants to be fully immersed into JavaScript.

JavaScript In Practice: ES6 And Beyond

Promises represent the eventual result of an asynchronous operation. They give us a way to handle asynchronous processing in a more synchronous fashion. A promise represents a value we can handle in the future, with the following guarantees:

- Promises are immutable.
- Promises are either kept or broken.
- When a promise is kept, we are guaranteed to receive a value.
- When a promise is broken, we are guaranteed to receive the reason why the promise cannot be fulfilled.

# Promise States

- `pending`: may transition to `fulfilled` or `rejected`
- `fulfilled` (kept promise): must have a value
- `rejected` (broken promise): must have a reason for rejecting the promise
