tslint-config-prettier disables all TSLint rules that might conflict with Prettier. This ensures consistent code formatting by delegating that responsibility solely to Prettier, preventing linting errors that conflict with Prettier's formatting. It simplifies TypeScript linting setup by eliminating rule conflicts, leading to cleaner, more maintainable projects. Effectively, it streamlines the process, allowing developers to focus on code logic instead of formatting squabbles between linters and formatters.
