- Simple linter, based on the Acorn [1] parser module
-
- All of the existing linters either cramp my style or have huge
- dependencies (Closure). So here's a very simple, non-invasive one
- that only spots
-
-  - missing semicolons and trailing commas
-  - variables or properties that are reserved words
-  - assigning to a variable you didn't declare
