node-green's Issues

Add support for latest ES_VERSIONS (eg. everything after ES2018)

Looking at the code here, it will only check against a hardcoded list of ES_VERSIONS:

node-green/src/index.ts

Lines 3 to 9 in 8e9480b

	const ES_VERSIONS = [
	'ESNEXT',
	'ES2018',
	'ES2017',
	'ES2016',
	'ES2015',
	]

node-green/src/index.ts

Line 48 in 8e9480b

ES_VERSIONS.forEach(ver => {

Yet looking at the .json data for a recent (19.1.0) version of node in node-compat-table, there are many more keys supported:

• https://github.com/williamkapke/node-compat-table/blob/gh-pages/results/v8/19.1.0.json

⇒  curl --silent https://raw.githubusercontent.com/williamkapke/node-compat-table/gh-pages/results/v8/19.1.0.json | jq 'keys'
[
  "ES2015",
  "ES2016",
  "ES2017",
  "ES2018",
  "ES2019",
  "ES2020",
  "ES2021",
  "ES2022",
  "ES2023",
  "ESNEXT",
  "_engine",
  "_version"
]

It would be great if you could update this package (and ensure the node-green-cli uses the newer version) so that we can check features that only came into existence in these newer versions.

Ideally we could probably do away with the hardcoded ES_VERSIONS and just extract the keys to check automagically from the .json, something like this might work:

const esVersions = Object.keys(result).filter(key => !key.startsWith('_')).reverse();
