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

When using symbols as identifiers for objects, we don't have to set up a global registry of available identifiers. We also save the creation of a new identifier, as all we need to do is create a `Symbol()`.

The same holds for external libraries. 

In the next lesson, we'll talk about some well-known symbols and how they change the behavior of your code.

# Well-known Symbols

There are some [well-known symbols](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Symbol#Well-known_symbols) defined to access and modify internal JavaScript behavior. For example, you can redefine built-in methods, operators, and loops. Redefining standard language behavior usually confuses other developers. Ask yourself, will this skill move you forward in your career?

We will not focus on well-known symbols in this section. If there is a valid use case for it, I will signal it in the corresponding lesson. Otherwise, I suggest staying away from manipulating the expected behavior of your code.

Before learning newer concepts, let's solve some exercises.
