JS 依照元素出現數量排序
同樣是最近遇到的狀況，需要利用陣列內元素出現的數量進行排序，以下為範例程式：
var array = ["1", "2", "4", "5", "2", "4", "2", "3"];
var str = array.toString();
var filter = [];
var result = [];
document.write("原始陣列：" + array + "<br>");
var get = function (str, tar, arr, tmp) {
if (str.indexOf(tar) >= 0) {
tmp = str.slice(str.indexOf(tar) + 1);
arr.push(tar);
get(tmp, tar, arr, tmp);
}
return arr;
}
for (i in array) {
var elm = [];
var tmp;
var fstr = filter.join();
if (fstr.indexOf(array[i]) >= 0) {
continue;
} else {
var tmp_arr = get(str, array[i], elm, tmp);
result.push(tmp_arr.length + ':' + tmp_arr[0]);
filter.push(array[i]);
}
}
result.sort();
result.reverse();
//按照出現次數排序，不刪除重複元素
var finishArray = [];
for (index in result) {
var show = result[index].split(':');
for (i = 0; i < show[0]; i++) {
finishArray.push(show[1]);
}
}
document.write("按出現次數排序，不刪除重複元素：" + finishArray + "<br>");
//按照出現次數排序，刪除重複元素
var finishArray = [];
for (index in result) {
var show = result[index].split(':');
finishArray.push(show[1]);
}
document.write("按出現次數排序，刪除重複元素：" + finishArray + "<br>");
輸出結果：
原始陣列：1,2,4,5,2,4,2,3 按出現次數排序，不刪除重複元素：2,2,2,4,4,5,3,1 按出現次數排序，刪除重複元素：2,4,5,3,1

Reasons Why Online Casinos Are Booming
The surge in popularity of online casinos is driven by several factors. A key benefit is that online casinos are available anytime, anywhere. While land-based casinos have restrictions, online platforms operate 24/7, letting players enjoy their favorite games at any time.
Another major reason for their popularity is the sheer variety of games. Physical casinos may offer a few hundred games at best, but digital platforms feature thousands. Players can enjoy everything from nostalgic one-armed bandits to modern 3D slots packed with special features.

Unlocking Casino Bonuses
Bonuses and special offers make online gambling even more enticing. Signing up usually comes with exciting perks like extra cash or free slot spins. Loyal customers are rewarded with tiered programs, reloading bonuses, and special incentives.

While many casino games are based purely on luck, some require skill and strategy. In games like poker, knowledge and tactics can give players a significant edge over less experienced opponents. If you prefer a fast-paced, unpredictable experience, slots and roulette provide thrilling, luck-based gameplay.
Responsible Gambling & Choosing a Safe Casino
As exciting as online gambling can be, it’s essential to practice responsible gaming. Smart bankroll management and self-control help players maintain a healthy approach to gambling. Licensed casinos provide responsible gambling measures, such as cooling-off periods and withdrawal restrictions, to help players stay in control.
