Fork this gist and answer the following questions:

  • What is ES6?
    -This first major update to JavaScript since 2009.
  • What is Transpilation and how does it relate to ES6?
    • A transcompiler takes the source code of a program as in input, and converts it to equivalant code in another language as the output. Babel does this for different versions of JavaScript, allowing code written in ES6 to be converted to an older version of JavaScript from a more simple and rugged time, when all of the fancy new features weren't available. Because we must never break the Space Jam website.
  • Looking at the ES6 Features link below, discuss one update from ES5 and if it seems useful/superfluous.
    • The inclusion of 'let' and 'const' seems useful. The 'let' keywords allows block-scoping of non-hoisted variables. Using the 'const' keyword, you can assign a value much like with 'var', but it cannot be reassigned. These two new features will help prevent scope-related bugs, and provide functionality that most other programming languages already offer.
