 Linters have two categories of rules:

 Prettier alleviates the need for this whole category of rules! Prettier is going to reprint the entire program from scratch in a consistent way, so it's not possible for the programmer to make a mistake there anymore :)
 
-**Code-quality rules**: eg [no-unused-vars](http://eslint.org/docs/rules/no-unused-vars), [no-extra-bind](http://eslint.org/docs/rules/no-extra-bind), [no-implicit-globals](http://eslint.org/docs/rules/no-implicit-globals), [prefer-promise-reject-errors](http://eslint.org/docs/rules/prefer-promise-reject-errors)...

 Prettier does nothing to help with those kind of rules. They are also the most important ones provided by linters as they are likely to catch real bugs with your code!

+This printer is a fork of [recast](https://github.com/benjamn/recast)'s printer with its algorithm replaced by the one described by Wadler in "[A prettier printer](https://homepages.inf.ed.ac.uk/wadler/papers/prettier/prettier.pdf)". There still may be leftover code from recast that needs to be cleaned up.
 
 The basic idea is that the printer takes an AST and returns an intermediate representation of the output, and the printer uses that to generate a string. The advantage is that the printer can "measure" the IR and see if the output is going to fit on a line, and break if not.
