-- If you want to downgrade this syntax to ensure good code compatibility, you can compile the specified module through the `source.include` config.
-- If you don't want to downgrade the syntax, you can adjust the project's browserslist to match the syntax.
-- If you don't want to check the syntax of specified files, you can use the `exclude` option to exclude the files to be checked.
