Last active August 13, 2019 16:01

Jawaban untuk Jawa Barat Digital Services, tentang fixing bugs di append sebuah element menggunakan looping.

	/*
	* catatan : untuk memperbaiki bugs di appenChild ini ada 2 cara yaitu
	* 1. bisa mengubah method get element nya dengan method
	* var allDivs = document.querySelectorAll("div");
	* 2. menggunakan method yang sama akan tetapi membuat variable tambahan untuk menampung sebuah length, dan hasil tampungan
	* tersebut bisa digunakan sebagai jumlah limit loop nya.
	* var allDivs = document.getElementsByTagName("div");
	* var length = allDivs.length;
