JavaScript Array sort: Sorting an Array More Effectively, The sort() method will sort elements based on the return value of the compare() function with the following rules: If compare(a,b) is less than zero, the sort() method sorts a to a lower index than b . If compare(a,b) is greater than zero, the sort() method sort b to a lower index than a , i.e., b will come first. Sorting a whole array is a very inefficient method if you only want to find the highest (or lowest) value. Using Math.max() on an Array You can use Math.max.apply to find the highest number in an array:

const toSort = 'sky is blue today';

const sorted = toSort.split(' ').sort((a,b) => a.length < b.length ? -1: 1).join(' ');


Array.prototype.sort(), The sort() method sorts the elements of an array in place and returns the If compareFunction(a, b) returns less than 0, sort a to an index lower� YMMV on how you feel about adding functions to the Array prototype and mutating arrays inline, but this allows sorting of an array of any objects that can be compared. It takes an optional function that can be used for sorting, much like Array.prototype.sort. An example,

You can try like this

var arr = "sky is blue today";

var result  = arr.split(' ').sort((a, b) => a.length - b.length).join(' ');

JavaScript Array Sort, However, after you have sorted an array, you can use the index to obtain the highest and lowest values. and points[points.length-1] contains the highest value. 3. Merge Sorting Algorithm. Similar to Bubble Sort and Selection Sort, Merge sort is one of the popular sorting algorithms in computer science, you can implement it in most programming languages, and it has good performance without it being too needy on resources.

Sort an integer array and return the index values in order of size , javascript isn't that much different. You should be able to figure it out. Code ( csharp):. int[]� The length property of an object which is an instance of type Array sets or returns the number of elements in that array. The value is an unsigned, 32-bit integer that is always numerically greater than the highest index in the array.

How to find the index where a number belongs in an array in , Our goal is to return the index of our input number after it is sorted an element to an array using .push() , it returns the length of the new array. At the implementation level, JavaScript's arrays actually store their elements as standard object properties, using the array index as the property name. The length property is special. It always returns the index of the last element plus one. (In the example below, 'Dusty' is indexed at 30, so cats.length returns 30 + 1).
