  • matches-shorthand: Prefer matches shorthand syntax
  • preferred-alias: Preferred aliases
  • prefer-chain: Prefer chain over nested lodash calls
  • no-single-chain: Prevent chaining syntax for single method, e.g. _(x).map().value()
  • prefer-reject: Prefer _.reject over filter with !(expression) or x.prop1 !== value
  • prefer-filter: Prefer _.filter over _.forEach with an if statement inside.
  • no-unnecessary-bind: Prefer passing thisArg over binding.
  • unwrap: Prevent chaining without evaluation via value() or non-chainable methods like max().,
  • prefer-compact: Prefer _.compact over _.filter for only truthy values.
  • no-double-unwrap: Do not use .value() on chains that have already ended (e.g. with max() or reduce())
  • prefer-map: Prefer _.map over _.forEach with a push inside.
  • prefer-wrapper-method: Prefer using array and string methods in the chain and not the initial value, e.g. _(str).split(' ')...
  • prefer-invoke: Prefer using _.invoke over _.map with a method call inside.
  • prefer-thru: Prefer using _.prototype.thru in the chain and not call functions in the initial value, e.g. _(x).thru(f).map(g)...
  • prefer-lodash-chain: Prefer using Lodash chains (e.g. _.map) over native and mixed chains.
  • prefer-lodash-method: Prefer using Lodash collection methods (e.g. _.map) over native array methods.
  • prefer-lodash-typecheck: Prefer using _.is* methods over typeof and instanceof checks when applicable.
