Joe Lencioni	dc7e7e77f2	Reverse rule on string concatenation for long lines (#995 ) Broken and concatenated long strings are painful to work with and produce less readable and searchable code. I think we should reverse this rule. Unfortunately, the max-len rule currently does not allow for this, but there is currently a proposal to add an option to ESLint's max-len rule that would allow for strings to be ignored. https://github.com/eslint/eslint/issues/5805 There have also been discussions around performance of string concatenation (https://github.com/airbnb/javascript/issues/40), but I don't think that is very relevant here so I removed the links to them.	2016-08-04 09:53:09 -07:00
Joe Lencioni	6d2fc89bd1	Add template literal "bad" example to single quotes guideline There has been some confusion around whether we should use single quotes or template literals. To help avoid this confusion, I am adding a "bad" example to the single quotes guideline. This rule is already enforced by the quotes linter rule. Generally, we want code to clearly express developer intention. Using template literals communicates that you intend to use some of the features that template literals offer (e.g. interpolation). Fixes #992	2016-08-04 09:38:12 -07:00
Joe Lencioni	bfc842e3ad	Remove rules about reserved words In `53b4173b` we removed the ES5 guide which contains a lot of guidelines that are no longer very relevant for us. Similarly, some folks have raised the relevance of these rules about reserved words, given that we are now living in an age where ES3 support has mostly waned and transpilers such as Babel are widely adopted and pave over these issues. This seems like a good opportunity to simplify. Fixes #61	2016-08-03 14:41:16 -07:00

Joe Lencioni	52a2da4182	Add curlies around ref function body The example we have here uses an implicit return, which is forbidden when assigning. This triggers the no-return-assign rule. Fixes #980	2016-08-02 09:09:12 -07:00
