Apa perbedaan JavaScript dan PCRE2?

JavaScript menggunakan RegExp bawaan browser. PCRE2 mendukung fitur lanjutan seperti lookbehind, grup atomik, dan rekursi.

JavaScript: g, i, m, s, u. PCRE2 tambahan: x, A, D.

Pustaka menyediakan 30+ template. Sebagian besar disederhanakan.

Ya. JavaScript: $1, $2. PCRE2: \\1, \\2 atau ${1}, ${2}.

Otomatis kembali ke JavaScript. Periksa koneksi jaringan.
