@putout/plugin-remove-useless-new

????Putout plugin adds ability to remove useless operator new. Which has no sense for BigInt, Boolean, String, Number, Object, RegExp, Error:

Thus the function call Error(…) is equivalent to the object creation expression new Error(…) with the same arguments.

(c) https://262.ecma-international.org/12.0/#sec-error-constructor

And Symbol cannot be used with new, as it is primitive. Part of @putout/plugin-new.
