How to detect unused variables in Typescript?

Question

Is there a way to detect unused variables in Typescript (something like ESLint in Javascript)?

Answer 1

As of version 2.0, Typescript has built-in support for detecting unused local variables and parameters. The compiler flags are as follows:

--noUnusedLocals                    Report Errors on Unused Locals.
--noUnusedParameters                Report Errors on Unused Parameters.
