ES6 Features used in the source

In the source code for Video.js we use ES6 -- new syntax features of the JavaScript language. When building the final video.js file these features get converted (transpiled) to JavaScript that is compatible with older browsers. If you're contributing to video.js, here's a guide of the features we use.

• Modules (import/export)
• let and const
• Destructuring

Modules

let and const

Block-scoped binding constructs. let is the new var. const is single-assignment. Static restrictions prevent use before assignment babeljs.io

Destructuring
