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

Maps represent key-value pairs, similar to objects. 

You may be wondering why we need a map data structure if objects can also be used as maps. The answer is simple: maps can have keys of any type, and the keys are not converted to strings. Therefore, `0` and `'0'` are two different, and valid keys.

Objects are also valid keys for maps. They are not converted to `'[object Object]'`. Note though, that objects are reference types. Therefore, using the `{}` object literal twice as keys will result in two different entries in the map.

We can build maps in multiple ways. We can either use the `set` method to add values to the map or pass an array of key-value pairs to the map constructor.
