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 ...
Example 3: Sorting Numbers Numerically Since all non-undefined elements are converted to strings before sorting them, we cannot sort numbers using their numeric value by default. Let's see how we can implement this using a custom function. // numeric sorting// define arrayvarpriceList = [1000...
Sort numbers (numerically and ascending) - sort() Sort numbers (numerically and descending) - sort() Add an element to position 2 in an array - splice() Convert an array to a string - toString() Add new elements to the beginning of an array - unshift() ...

数据消费者:另一方面,您有一整类构造和算法,它们只需要顺序访问它们的输入:一次一个值,直到所有值都被访问。例如,for-of循环和展开到函数调用(通过...)。 迭代协议通过接口Iterable连接这两组:数据源通过它顺序地“传递其内容”;数据消费者通过它获取其输入。
// JavaScript also supports arrays (numerically indexed lists) of values: let primes = [2, 3, 5, 7]; // An array of 4 values, delimited with [ and ]. primes[0] // => 2: the first element (index 0) of the array. primes.length // => 4: how many elements in the array. ...

The function calculates 40 - 100 (a - b), and since the result is negative (-60), the sort function will sort 40 as a value lower than 100.You can use this code snippet to experiment with numerically and alphabetically sorting:
a.sort(); // The object-oriented version of sort(a). 方法定义在第九章中介绍。技术上,只有 JavaScript 对象有方法。但是数字、字符串、布尔值和符号值的行为就好像它们有方法一样。在 JavaScript 中,只有null和undefined是不能调用方法的值。 JavaScript 的对象类型是可变的,而其原始类型是不可变的。可变类型...
