28. ECMAScript 6+ (ES 2015+) Styles

28.1 These are the collections to the various ES6+ features.

• Arrow Functions
• Classes
• Object Shorthand
• Object Concise
• Object Computed Properties
• Template Strings
• Destructuring
• Default Parameters
• Rest
• Array Spreads
• Let and Const
• Exponentiation Operator
• Iterators and Generators
• Modules

28.2 Do not use TC39 proposals that have not reached stage 3.

Why? They are not finalized, and they are subject to change or to be withdrawn entirely. We want to use JavaScript, and proposals are not JavaScript yet.
