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

A **generator** is a special function that returns an iterator. There are some differences between generator functions and regular functions:

- There is an `*` after the `function` keyword.
- Generator functions create iterators.
- We use the `yield` keyword in the created iterator function. By writing `yield v`, the iterator returns `{ value: v, done: false }` as a value.
- We can also use the return keyword to end the iteration. Similar to iterators, the returned value won't be enumerated by a data consumer.
- The yielded result is the next value of the iteration process. Execution of the generator function is stopped at the point of yielding. Once a data consumer asks for another value, execution of the generator function is resumed by executing the statement after the last yield.
