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

How Nigeria’s biggest city became the world’s hottest winter party destination
casino bonus
It’s a world of endless parties and sleepless nights. A relentless celebration that turns West Africa – and especially Nigeria’s largest city, Lagos – into one of the hottest destinations on the continent, if not the planet, right in the middle of winter.
Detty December is a magical time between December and early January when diaspora communities and tourists flock to Ghana, Nigeria and South Africa for an unforgettable experience filled with flavourful food, soulful African music and sunshine.
Beach parties, festivals and top-tier performances fuel the energy, while fashion takes center stage, with everyone dressing to impress.
Nearly two-thirds of Nigeria’s population is under 25, according to the United Nations Population Fund, making this one of the world’s youngest countries.
Internationally renowned Afrobeats performers and foreign artists make surprise appearances. DJs take to the streets, blasting powerful beats from consoles mounted atop bright yellow minibuses.
At times it’s all-consuming. Good luck getting hair salon appointments, affordable air tickets or navigating Lagos’ already notorious traffic when the party crowds are in town.
Detty December (“detty” is a playful corruption of “dirty”) is a triumphant celebration of culture, music and good vibes that has evolved in recent years during the traditional holidays influx of diaspora returnees, which heightened in 2018 when Ghana ran a launched a successful “Year of Return” campaign actively encouraging people to visit their ancestral homelands.
It’s gathered pace over the past five years, gaining an international reputation, as IJGBs (“I Just Got Backs”) and their friends arrive in batches, eager to unwind and blow off steam after the fast-paced, hard-working year they’ve had overseas.
For many in the vast Nigerian diaspora, it is a deeply personal homecoming, a chance to reconnect with their heritage, traditions and families while immersing themselves in the lively energy of Nigerian life.
