2
Detect the assignation of a require import to a var such as 'var module = require("module")'. It should be replaced by the ES2015-style or 'import foo = require("module")' imports
Detect any non-null assertions after an optional chain, as optional chains can return 'undefined' and this can introduce some serious type safety issues
Detect all assignments of "this" to variables as there are alternatives to use this in different scopes, for example replacing anonymous functions with arrow functions
Detect the assignment of a require import to a var such as 'var module = require("module")' as it should be replaced by the ES2015-style or 'import foo = require("module")' imports
Prefer the use of "as const" when trying to define a primitive value as a type (e.g instead of "let bar: 2 = 2;" use "let bar = 2 as const", and now 2 will be the assigned type of "bar")

fp-no-rest-parameters
Unknonwn
2
Detect any definition of "rest parameters" (e.g function sum(...numbers) where numbers represent the arguments passed directly to the sum function), the parameters should be explicit (e.g "function sum(numbers)" where numbers can be a list of values)
fp-no-throw
Unknonwn
2
Instead of throwing an error, return an object containing the description of the error, or use a tool like Either that you can find in some functional libraries.

Control characters are special, invisible characters in the ASCII range 0-31. These characters are rarely used in JavaScript strings so a regular expression containing these characters is most likely a mistake.
Empty block statements, while not technically errors, usually occur due to refactoring that wasn't completed. They can cause confusion when reading code.
Disallows sparse array literals which have "holes" where commas are not preceded by elements. It does not apply to a trailing comma following the last element.
By default this rule prevents passing of props that add lots of complexity (className, style) to Components.
