How to use the just-scripts.argv function in just-scripts

task('ts', () => {
    return argv().commonjs
      ? 'ts:commonjs-only'
      : parallel('ts:commonjs', 'ts:esm', condition('ts:amd', () => argv().production && !argv().min));
  });

amd: () => {
    const extraOptions = getExtraTscParams(argv());
    return tscTask({ ...extraOptions, outDir: 'lib-amd', module: 'amd' });
  },
  commonjsOnly: () => {

task('ts', () => {
  return tscTask({
    pretty: true,
    ...(argv().production && {
      inlineSources: true,
      sourceRoot: path.relative(libPath, srcPath),
    }),
    target: 'es5',
    module: 'commonjs',
  });
});
