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

Для эффективного и безопасного выхода из запоя необходимо квалифицированное лечение, включающее детоксикацию организма, восстановление работы внутренних органов и поддержку психоэмоционального состояния. В этом случае важно обратиться к специалистам, которые смогут подобрать оптимальные методы терапии, исходя из состояния пациента. Один из наиболее эффективных способов снятия алкогольной интоксикации – это внутривенная инфузионная терапия (капельницы), позволяющая быстро очистить организм от токсинов, восстановить водно-солевой баланс и улучшить общее самочувствие.

The rise of online casinos has revolutionized the gambling industry, allowing players to enjoy high-quality gaming without leaving their homes. Gone are the days when gambling was limited to land-based establishments, because online platforms offer everything from classic slots to live dealer games.
Reasons Why Online Casinos Are Booming
There are many reasons why online casinos have gained massive traction. One of the biggest advantages is accessibility. Unlike physical casinos that have operating hours, internet-based casinos never close, ensuring round-the-clock entertainment.
Another major reason for their popularity is the sheer variety of games. While land-based venues have space constraints, online casinos provide an endless assortment of games. Whether you love old-school slots or cinematic video games, there’s something for everyone.

How Online Casinos Keep Players Engaged
One of the biggest draws of online casinos is the generous promotions and bonuses. Many platforms offer newcomers fantastic welcome packages, boosting their bankroll instantly. Loyal customers are rewarded with tiered programs, reloading bonuses, and special incentives.
Luck vs. Skill in Online Gambling
Depending on your preferences, you can choose between pure chance games or those where skill makes a difference. For those who enjoy strategic play, poker offers opportunities to refine skills and increase winning chances. On the other hand, slot machines and roulette rely entirely on chance, making them ideal for casual players looking for fun and excitement.
Responsible Gambling & Choosing a Safe Casino
To ensure a positive experience, it’s vital to play responsibly and within limits. By setting strict financial limits and staying disciplined, players can prevent gambling from becoming a problem. Reputable platforms also promote responsible gaming by offering tools like deposit limits, self-exclusion, and links to gambling support organizations.
