hyf-lint is a simple tool to perform rudimentary checks on the JavaScript homework of students, with a focus on naming conventions. It is not a replacement for ESLint.

It can generate the following messages (see file src/constants.js for an up-to-date list):

• SHOUT_CASE variables expected to be const.
• Expected camelCase name.
• Expected a PascalCase name following ‘new’.
• Expected let or const instead of var.
• Detected nested function declaration.
• Detected potentially commented-out code.
• Detected disabled ESLint rule(s).
• Detected deprecated HTML Element.
• Detected PascalCase function name.
• Detected noise word as name prefix or suffix.
• Detected single letter name.
• Detected ‘x the Unknown’ as a name.
• Detected ‘l’ as a name: easily confused with the number ‘1’.
• Detected numeric suffix in identifier.
• Detected iterative for-loop: suggest array method.
