This is not what we want when we need to sort an array of strings in descending order, however, it's exactly what we want when sorting string arrays in ascending order. If the return value of the compare function is greater than0, then sortbbeforea. ...
Sort an array of strings alphabetically# 需求: Write a function that takes an array of strings as argument Sort the array elements alphabetically Return the result 我的提交(作者答案) functionmyFunction(arr) {returnarr.sort();} 涉及知识(字母排序方法)# 字母排序方法# 使用Array.prototype.sort()方...
In the next example, we sort an array of strings by its length. main.js let words = ['brown', 'war', 'a', 'falcon', 'tradition', 'no', 'boot', 'ellipse', 'strength']; let bylen = (e1, e2) => e1.length - e2.length; let bylendesc = (e1, e2) => e2.length - e1...
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 stringsvarnames = ["Adam","Jeffrey","Fabiano","Danil","Ben"];functionlen_compare(a, b){returna....

Sort can automatically arrange items in an array. In this lesson we look at the basics including how to sort an array of strings alphabetically and the correct way to perform a numerical sort on an array of numbers. We finish as always with a practical use-case that shows not onlysortin...
跟大多数排序函数类似，Array.prototype.sort(fn(a,b))需要一个包含两个测试参数的回调函数,其返回值如下：a在b之前则返回值小于0a和b相等则返回值是0a在b之后则返回值小于0 [9,80,3,10,5,6].sort()// <- [10, 3, 5, 6, 80, 9][9,80,3,10,5,6].sort(function (a, b) { return ...
除了上面三个对象,Javascript 还拥有 Date、Array、Math 等内置对象,这三个经常显示使用,所以非常熟悉,知道了内置对象就可以看看上面例子是怎么回事儿了。 只要是引用了字符串的属性和方法,Javascript 就会将字符串值通过 new String(s)的方式转为内置对象 String,一旦引用结束,这个对象就会销毁。所以上面代码在使用的...
Use the same trick to sort an array descending: Example constpoints = [40,100,1,5,25,10]; points.sort(function(a, b){returnb - a}); Try it Yourself » The Compare Function The purpose of the compare function is to define an alternative sort order. ...
