`no-useless-predicate` | Detects redundant conditions that are either always true or always false. *requires type information* | Combination of TSLint's `strict-type-predicates`, `typeof-compare` and parts of `strict-boolean-expressions`.
[`no-useless-spread](docs/no-useless-spread.md)` | :wrench: Disallows redundant array and object spread. | There's no similar TSLint rule.
`parameter-properties` | Enforces or disallows the use of parameter properties. This rule is **not** enabled in `wotan:recommended`. | TSlint only has `no-parameter-properties` to disallow all parameter properties and has no autofixer.
`prefer-const` | Prefer `const` for variables that are never reassigned. Use option `{destructuring: "any"}` if you want to see failures for each identifier of a destructuring, even if not all of them can be constants. The default is `{destructuring: "all"}`. | TSLint's `prefer-const` rule gives some false positives for merged declarations and variables used in before being declared which results in a compiler error after fixing.
`prefer-dot-notation` | Prefer `obj.foo` over `obj['foo']` where possible. | Same as TSLint's `no-string-literal` rule, but more performant.

`prefer-object-spread` | Prefer object spread over `Object.assign` for copying properties to a new object. *requires type information* | Performance, and better handling of parens in fixer and avoids false positives that would cause a compile error when fixed.
`return-never-call` | Prefer `return neverReturns();` or `throw neverReturns();` over plain calls to `neverReturns();` to enable better control flow analysis and type inference. | TSLint has no similar rule.
`syntaxcheck` | Reports syntax errors as lint errors. This rule is **not** enabled in `wotan:recommended`. *requires type information* | Used to be part of the deprecated `tslint --type-check`
`trailing-newline` | Requires a line break at the end of each file. | Nothing fancy here :(
`try-catch-return-await` | Companion of `no-return-await` because inside a try-catch block you should await returned promises to correctly enter the catch on rejection and/or the finally block after completion. *requires type information* | TSLint has no similar rule.
`type-assertion` | Enforces a single type assertion style: "classic" `<T>obj` or "as" `obj as T`. This rule is **not** enabled in `wotan:recommended`. | TSLint has only `no-angle-bracket-type-assertion` which always enforces `as` and forgets to add parens when autofixing some cases.
`typecheck` | TypeScript's compiler errors as lint errors. This rule is **not** enabled in `wotan:recommended`. *requires type information* | Like the deprecated `tslint --type-check` but formatted and can be disabled like any other rule.
