@phryneas/ts-version
A little utility type package that allows you to access the current TypeScript version from your types.
import { TSVersion } from "@phryneas/ts-version";
type Version = `${TSVersion.Major}.${TSVersion.Minor}`;
type VersionDependentType = TSVersion.AtLeast<4, 7> extends true
? "we're in the future!"
: "it's the stone age!";
