TypeScript Array sort() Method

The sort() method in TypeScript sorts the elements of an array and returns the sorted array. By default, it sorts an array in ascending order. It can take an optional compareFunction to define the sort order, allowing for custom sorting logic.

Syntax

array.sort( compareFunction )

Parameter: This method accepts a single parameter as mentioned above and described below: 

• compareFunction : This parameter is the function that defines the sort order

Return Value: This method returns the sorted array. 

The below example illustrates the  Array sort() method in TypeScriptJS:

Example 1: Sorting Numbers

In this example we initializes an array arr with numbers, uses the sort() method to sort the array in ascending order

let arr: number[] = [11, 23, 7, 89, 98];
arr.sort((a, b) => a - b);
console.log(arr);

Output: 

[7, 11, 23, 89, 98]

Example 2: Sorting Characters

In this example we initializes an array chars with characters, sorts the array in ascending alphabetical order using the sort() method.

let chars: string[] = ['G', 'e', 'e', 'k', 's', 'f', 'o', 'r', 'G', 'e', 'e', 'k', 's'];
chars.sort();
console.log(chars);

Output: 

["G", "G", "e", "e", "e", "e", "f", "k", "k", "o", "r", "s", "s"]
