To sort an array in TypeScript we could use Array.sort() function. TheArray.sort()is an inbuilt TypeScript function that is used to sort the elements of an array.

Syntax:

array.sort(compareFunction)

Below are the places where we could use the sort() function:

Sorting array of numbers
Sorting Array of Strings
Sorting Array of Objects

Sorting Array of Numbers

Example: In this example, we have an array of numbers, and we use the sort method with a custom comparison function to sort the array in ascending order.

Javascript

const numbers: number[] = [4, 2, 7, 1, 9, 5];

numbers.sort((a, b) => a - b);

console.log("Sorted Numbers: ", numbers);

Output:

Sorted Numbers: [1, 2, 4, 5, 7, 9]

Sorting Array of Strings

Example: In this example, we have an array of strings, and we use the sort method to sort the strings in default lexicographic order.

Javascript

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

fruits.sort();

console.log("Sorted Fruits: ", fruits);

Output:

Sorted Fruits: [ 'Apple', 'Banana', 'Mango', 'Orange' ]

Sorting Array of Objects

Example: In this example, we have an array of people with name and age properties. We use the sort method with a custom comparison function to sort the array based on the age property in ascending order.

Javascript

interface Person {

name: string;

age: number;

}

const people: Person[] = [

{ name: "Alice", age: 25 },

{ name: "Bob", age: 30 },

{ name: "Charlie", age: 22 },

{ name: "David", age: 28 }

];

people.sort((a, b) => a.age - b.age);

console.log("Sorted People by Age: ", people);

Output:

Sorted People by Age: [ 
 { name: 'Charlie', age: 22 }, 
 { name: 'Alice', age: 25 }, 
 { name: 'David', age: 28 }, 
 { name: 'Bob', age: 30 }
 ]

How to move Null Values at the end Regardless of the Sorting Direction in TypeScript ? A few times, we face situations where we need to sort values with null values in them.

What is the most efficient way to sort an array? ›

Quicksort. Quicksort is generally thought of as the most efficient 'general' sorting algorithm, where nothing is known about the inputs to the array, and it's more efficient than insertion sort on large lists.

What is the best sorting algorithm for sorted array? ›

When the array is almost sorted, insertion sort can be preferred. When order of input is not known, merge sort is preferred as it has worst case time complexity of nlogn and it is stable as well. When the array is sorted, insertion and bubble sort gives complexity of n but quick sort gives complexity of n^2.

How to perform sorting in an array? ›

Steps

Select the first element of the list.
Compare the selected element with all other elements in the list.
For every comparison, if any element is smaller (or larger) than selected element, swap these two elements.
Repeat the same procedure with next position in the list till the entire list is sorted.

How to sort an array without using the sort method? ›

We traverse the whole array checking whether the next element from the current index is greater or not. If it is greater than the current element we swap both of the elements. We keep on repeating this process until our array is sorted.

What is the quickest algorithm to sort an array? ›

Quick sort is a widely used and efficient sorting algorithm that employs a divide-and-conquer approach to sort an array or list of elements. The basic idea behind quick sort is to select a 'pivot' element from the array and partition the elements into two sub-arrays: one incorporating elements less than the pivot.

What is the easiest sort array? ›

Bubble sort is one of the most straightforward sorting algorithms. In this sorting technique, we begin by comparing the first two elements of the array and checking if the first element is greater than the second element; if it is, we will swap those elements and move forward to the next element.

What is the optimized way to sort an array? ›

Quick sort is also known as a “partition sort.” This sorting algorithm is faster than the previous algorithms because this algorithm uses the concept of divide and conquer. First, we decide on a pivot element. We then find the correct index for this pivot position and divide the array into two subarrays.

Which is the fastest method to sort an almost sorted array? ›

Insertion sort is the clear winner on this initial condition. Bubble sort is fast, but insertion sort has lower overhead. Shell sort is fast because it is based on insertion sort. Merge sort, heap sort, and quick sort do not adapt to nearly sorted data.

What is the fastest sorting algorithm in Javascript? ›

As the name suggests, Quicksort is one of the fastest sorting algorithms. The Quicksort algorithm takes an array of values, chooses one of the values as the 'pivot' element, and moves the other values so that lower values are on the left of the pivot element, and higher values are on the right of it.
