Breaking: Implement 'ecmaVersion: latest' (fixes #495) #499

Closed nzakas closed 3 years ago

nzakas commented 3 years ago

This is the implementation for #495, which:

  1. Allows ecmaVersion: "latest" as a valid value. Internally, this is just normalized to latestEcmaVersion, as that was the simplest way to validate this value.
  2. Sets the default ecmaVersion to latestEcmaVersion.

Added the missing test.

Please see my note on https://github.com/eslint/eslint/pull/14622#issuecomment-856162389 about keeping the default ecmaVersion for Espree at 5.

OK, it looks like we are good to move forward with this based on the latest changes to eslint/eslint#14622. :tada:
