JavaScript Array toSorted() Method

// Create an Array

const fruits = ["Banana", "Orange", "Apple", "Mango"];

// Sort the Array

const fruit2 = fruits.toSorted();

More Examples Blow !

The toSorted() method sorts the elements of an array in alphabetical order.

The toSorted() method returns a new array.

The toSorted() method does not overwrite the original array.

The toSorted() method is the copying version of the sort() method.

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".

You can fix this by providing a "compare function" (See examples below).

array.sort(compareFunction)

• function(a, b){return a-b}

When sort() compares two values, it sends the values to the compare function, and sorts the values according to the returned (negative, zero, positive) value.

Example:

The sort function will sort 40 as a value lower than 100.

When comparing 40 and 100, sort() calls the function(40,100).

The function calculates 40-100, and returns -60 (a negative value).

Sort and then reverse the order:

// Create an Array

const fruits = ["Banana", "Orange", "Apple", "Mango"];

// Sort the Array

const fruits2 = fruits.toSorted();

// Reverse the Array

fruits2.reverse();

Sort numbers in ascending order:

// Create an Array

const points = [40, 100, 1, 5, 25, 10];

// Sort the Array

let points2 = points.toSorted(function(a, b){return a-b});

Sort numbers in descending order:

// Create an Array

const points = [40, 100, 1, 5, 25, 10];

// Sort the Array

let points2 = points.toSorted(function(a, b){return b-a});

Find the lowest value:

// Create an Array

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in ascending order

let points2 = points.toSorted(function(a, b){return a-b});

let lowest = points2[0];

Find the highest value:

// Create an Array

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in descending order:

let points2 = points.toSorted(function(a, b){return b-a});

let highest = points2[0];

Find the highest value:

// Create an Array

const points = [40, 100, 1, 5, 25, 10];

// Sort the numbers in ascending order:

let points2 = points.toSorted(function(a, b){return a-b});

let highest = points2[points.length-1];

toSorted() is a JavaScript 2023 feature.

ES 2023 is supported in all modern browsers since July 2023:
