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

> Rule 1: use `let` for variables, and `const` for constants whenever possible. Use `var` only when you have to maintain legacy code.

The following rule is also worth keeping. 

> Rule 2: Always declare and initialize all your variables at the beginning of your scope.

Using rule 2 implies that you never have to face with the temporal dead zone. 

If you have a linter such as ESLint, set it up accordingly, so that it warns you when you violate the second rule.

If you stick to these two rules, you will get rid of most of the anomalies developers face.
