ee.Number.getInfo

Mengambil nilai objek ini dari server.

Jika tidak ada fungsi callback yang disediakan, permintaan akan dibuat secara sinkron. Jika callback disediakan, permintaan akan dibuat secara asinkron.

Mode asinkron lebih disarankan karena mode sinkron menghentikan semua kode lain (misalnya, UI Editor Kode EE) saat menunggu server. Untuk membuat permintaan asinkron, evaluate() lebih disukai daripada getInfo().

Menampilkan nilai yang dihitung dari objek ini.
