Assalamualaikum wr wb

    Hai sahabat calon programmer semuanya !
Pastinya ketika kita sedang mengembangkan sebuah website, kalian. tentu tidak akan terlepas dari penggunaan karakter khusus tertentu seperti ampersand (&), lebih kecil (<), lebih besar (>), titik koma (;) dan sebagainya. contoh, ketika anda ingin menambahkan menu "Qr → Qp" maka anda harus menambahkan "Qr &rarr; Qp" pada pengeditan HTML.
