I experimented with simplifying the eslint config to just use eslint-config-standard and eslint-config-prettier. There were too many errors to make it a quick change, but I did find a few useful rules we could adopt instead. --- * lint: Remove useless return statements http://eslint.org/docs/rules/no-useless-return * lint: Split declarations into multiple statements http://eslint.org/docs/rules/one-var * lint: Remove unneeded ternary operators http://eslint.org/docs/rules/no-unneeded-ternary * lint: Require symbol descriptions http://eslint.org/docs/rules/symbol-description * lint: Disallow declarations in nested blocks http://eslint.org/docs/rules/no-inner-declarations * lint: Disallow yoda conditions http://eslint.org/docs/rules/yoda * Revert "lint: Disallow yoda conditions" See discussion at https://github.com/prettier/prettier/pull/2401#discussion_r125750068 This reverts commit f3b568d5bd48a742460cb0f805d1be38d8f61a40.
