Sorting an ArrayThe sort() method sorts an array alphabetically:Example const fruits = ["Banana", "Orange", "Apple", "Mango"]; fruits.sort(); Try it Yourself » Reversing an ArrayThe reverse() method reverses the elements in an array:...
We can sort data alphabetically or numerically. The sort key specifies the criteria used to perform the sort. It is possible to sort objects by multiple keys. For instance, when sorting users, the names of the users could be used as primary sort key, and their occupation as the secondary ...
The Array reverse() Method Sort Compare Function Sorting alphabetically works well for strings ("Apple" comes before "Banana"). But, sorting numbers can produce incorrect results. "25" is bigger than "100", because "2" is bigger than "1". ...
All undefined elements are sorted to the end of the array andcompareFunctionis not called for them. Suppose we want to sort the abovenamesarray such that the longest name comes last, rather than sorting it alphabetically. We can do it in the following way: // custom sorting an array of ...
points.sort(function(a, b){returnb-a}); console.log( points[0] );//Get the lowest value in an array:varpoints = [40, 100, 1, 5, 25, 10]; console.log( points ); points.sort(function(a, b){returna-b}); console.log( points[0] );//Sort an array alphabetically, and then...
V. Sorting the array Just call thesort()method of the array to sort its elements. If no parameters are used when calling this method, the elements in the array will be sorted alphabetically. If we want to sort the elements according to the numeric values, we can first define a function...
Array.sort 默认的行为是这样的. 首先把所有的值强转成 string, 然后进行 string comparison. 第二题的中文字, 因为 string comparison 是比 Unicode 的号码, 而不是依据汉语拼音, 所以顺序就不对了. ['差' , '八', '阿'].map(v => v.charCodeAt(0));//[24046, 20843, 38463] ...

当比较 40 和 100 时,sort() 方法会调用比较函数 function(40,100)。 该函数计算 40-100 (a - b) ,然后返回 -60(负值)。 排序函数将把 40 排序为比 100 更低的值。 您可以使用下面的代码片段来测试数值和字母排序: Sort Alphabetically Sort Numerically var points = [40, 100, 1, 5, 25, 10...
