The built-insortfunction sorts the elements of an array in place and returns the sorted array. It takes an optional compare function as a parameter. The function is used to determine the order of the elements. It returns a negative value if the first argument is less than the second argumen...
Javascript arrays can contain different types of elements -strings,numbers,undefined, etc. It’s most often a good idea to have all items in an array be of the same type however.
let sortedArray = numbers.sort((a, b) => a - b); console.log( " numbers : ",numbers); // [1, 2, 3, 4, 5, 6, 7, 8, 9]; console.log( " sortedArray : ",sortedArray); // [1, 2, 3, 4, 5, 6, 7, 8, 9]; // To check the same reference console.log( numbers ...
To sort an array of numbers in JavaScript, call sort() method on this numeric array. sort() method sorts the array in-place and also returns the sorted array, where the numbers are sorted in ascending order. Since, the sort operation happens in-place, the order of the elements in input...

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 = [1000,50,2,7,14];// sort() using fun...
numbers.sort(function(a, b) { return a - b; }); console.log(numbers); // 正确输出: [2, 10, 21, 110] 这里,比较函数利用了数字的自然顺序进行排序。 二、深入数组排序 对于更复杂的数据结构,我们需要深入地了解排序的过程,并编写合适的比较函数。比如,我们要排序一个对象数组: ...

() will not work if the array consists of numeric values. Because the alphabetical order of numbers is different from their numeric order the sorted array may not be in the order you are expecting. For example, in a dictionary sort the number “11” would come before number “5”. This...
