sort() 方法就地对数组的元素进行排序,并返回对相同数组的引用。默认排序是将元素转换为字符串,然后按照它们的 UTF-16 码元值升序排序。
Note: The ECMAScript Standard, 10th edition (2019) algorithm mandates stable sorting, which means elements that compare equal must remain in their original order with respect to each other. This behaviour may not be respected by older browsers. compareFunction(a, b) must always return the same ...
If y is undefined, return −1. If the argument comparefn was not provided in the call to sort, go to step 7. Call comparefn with arguments x and y. Return Result(5). Call ToString(x). Call ToString(y). If Result(7) < Result(8), return −1. If Result(7) > Result(8), r...
以上90%引用自MDN 实例 //例1.字母排序 var a = new Array("banna","watermelon","orange","apple"); s.sort(); console.log(a) //输出 ["apple", "banna", "orange", "watermelon"] //没什么好说的,比较函数缺省,按照字母顺序升序排序 a<b<o<w ...
If you consult the MDN link for the collator in the references, you will find interesting uses aside from comparison functions, such as a melding of national language and date manipulation. Summary In this post, I showed how to cajoleArray.sort()into producing the following order. This… ...
Map sort by values in JS requires iterator object and an understanding of how they operate, and how the sort() function works intricately. The further readings are good starting points. Further Reading Array.prototype.sort() - JavaScript | MDN (mozilla.org) Map.prototype.entries() - JavaScript...
[1, 10, 2, 21] // Watch out that 10 comes before 2, // because '10' comes before '2' in Unicode code point order. var things = ['word', 'Word', '1 Word', '2 Words']; things.sort(); // ['1 Word', '2 Words', 'Word', 'word'] // In Unicode, numbers come before...
我们知道JavaScript中sort()是排序用的,比如:sort()的语法是:arr.sort([compareFunction]) 就是,我们可以指定排序函数(可选),如果省略,元素按照转换为的字符串的各个字符的Unicode位点进行排序。如果指明了compareFunction,那么数组会按照调用该函数的返回值排序。 对包含数字的数组排序,比较函数一般这么写: 然后,我很...
但要注意MDN对Array.prototype.sort()是这么描述的: sort() 方法用原地算法对数组的元素进行排序,并返回数组。默认排序顺序是在将元素转换为字符串,然后比较它们的UTF-16代码单元值序列... C语言 将一个数组按照从大到小排序的多种方法、冒泡排序 数组由大到小排列 --- 冒泡排序 实现一、数组---冒泡 实现二...
