Arti Kode \x (backslash x) dalam JavaScript

Pernah melihat kode-kode aneh atau membingungkan dalam JavaScript? Apa arti kode \x?

Pernah melihat kode-kode aneh atau membingungkan dalam JavaScript? Apa arti kode \x? Misalnya dalam artikel Mengubah-footer-template-droidpluss, seorang pengunjung bernama Tenri Baso bertanya kepada saya bagaimana membuat kode seperti berikut ini.

\x54\x65\x6D\x70\x6C\x61\x74\x65\x20\x6E\x6F\x74\x20\x62\x79\x20

Kode seperti itu adalah kode JavaScript yang terproteksi. Tujuannya mencegah pencurian kode JavaScript dan memangkas (mengecilkan) ukurannya.

Bagaimana Cara Memproteksi dan Mengecilkan Ukuran JavaScript?

Memproteksi dan mengecilkan ukuran JavaScript dapat dilakukan dengan bantuan Obfuscator. Silahkan kunjungi website Free JavaScript Obfuscator. Cara menggunakannya sangat mudah. Copy-Paste JavaScript sobat ke kolom Input Javascript code here:, setelah itu klik tombol OBFUSCATE. Hasilnya dikeluarkan pada kolom Obfuscated result:. Lihat screenshot di awal.

Sobat bisa lihat perbedaan JavaScript sebelum diproteksi dan sesudah diproteksi. Setelah diproteksi, kode JavaScript menjadi sangat sulit untuk dibaca. Iya, kan?

Bagaimana Membaca/Menguraikan JavaScript yang Diproteksi?

Jika sobat mendapati kode JavaScript seperi di atas (yang sudah diproteksi) tentu sangat sulit untuk mengeditnya. Tapi jangan khawatir, jika ada jalan memproteksi maka ada juga jalan untuk membuka proteksinya. Silahkan baca artikel Mengubah-footer-template-droidpluss untuk informasi lebih lanjut.

Selamat belajar :)
