Various Node Versions Support

[scurker]

This is probably in the early stages, so I apologize if this issue is premature. From the documentation, it looks like the intent is to support node 4 <=, but currently isn't transpiled down to support Node 4.

Node 4 & 5 (no destructuring)

/bin/babel-upgrade

const { isAcceptedNodeVersion, writePackageJSON, writeBabelRC } = require("../src");
      ^
SyntaxError: Unexpected token {

Node 6 (no async)

/src/index.js:59

async function writePackageJSON() {
      ^^^^^^^^
SyntaxError: Unexpected token function

Node 7 (no trailing/last commas)

/src/packageData.js:243

);
^
SyntaxError: Unexpected token )

Otherwise, everything has worked great in node 8 & 9 .

Yeah it's in the readme, didn't get to it yet. #11 (comment)

Or if someone wants to make a PR (use babel + target node 4 in the config with preset-env)
