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

The rise of online casinos has revolutionized the gambling industry, bringing players the excitement of real casinos straight to their screens. No longer do players need to visit physical casinos, because online platforms offer everything from classic slots to live dealer games.
Reasons Why Online Casinos Are Booming
The surge in popularity of online casinos is driven by several factors. One of the biggest advantages is accessibility. Unlike physical casinos that have operating hours, virtual casinos allow you to play whenever it suits you best.
The vast selection of games also contributes to the widespread appeal. Physical casinos may offer a few hundred games at best, but digital platforms feature thousands. From classic fruit machines to cutting-edge video slots with immersive themes, the choices are practically limitless.

Bonuses, Rewards, and Promotions
The abundance of promotions is one of the key benefits of playing at online casinos. Signing up usually comes with exciting perks like extra cash or free slot spins. Regular players can take advantage of loyalty programs, cashback deals, and exclusive VIP rewards.
Luck vs. Skill in Online Gambling
Not all casino games are about luck—some demand strategic thinking and expertise. Poker, for instance, is a game of skill where experienced players can outplay beginners by reading opponents and making calculated decisions. On the other hand, slot machines and roulette rely entirely on chance, making them ideal for casual players looking for fun and excitement.
How to Gamble Responsibly Online
As exciting as online gambling can be, it’s essential to practice responsible gaming. By setting strict financial limits and staying disciplined, players can prevent gambling from becoming a problem. Licensed casinos provide responsible gambling measures, such as cooling-off periods and withdrawal restrictions, to help players stay in control.
