[JavaScript] ES6/ES6 이란?

ECMAScript is a standardized version of JavaScript with the goal of unifying the language's specifications and features. As all major browsers and JavaScript-runtimes follow this specification, the term ECMAScript is interchangeable with the term JavaScript.

The most recent standardized version is called ECMAScript 6 (ES6), released in 2015. This new version of the language adds some powerful features that will be covered in this section of challenges, including:

• Arrow functions
• Classes
• Modules
• Promises
• Generators
• let and const [기존에는 var로 변수를 정의했었지]

Note
Not all browsers support ES6 features. If you use ES6 in your own projects, you may need to use a program (transpiler) to convert your ES6 code into ES5 until browsers support ES6.
