How to use sort method In Typescript

The sort method is a built-in array method in TypeScript that sorts the elements of an array in place. It takes a compare function as an argument, allowing you to define custom sorting criteria.

Example: Sorting an array in ascending and descending order using the sort function.

Javascript
let numbers: number[] = [4, 2, 7, 1, 9];

// Ascending order
numbers.sort((a, b) => a - b);
console.log("Ascending: "+ numbers); 

// Descending order
numbers.sort((a, b) => b - a);
console.log("Descending: "+ numbers);

Output:

Ascending: 1,2,4,7,9
Descending: 9,7,4,2,1

Method 1: Using sort method

The sort method is a built-in array method in TypeScript that sorts the elements of an array in place. It takes a compare function as an argument, allowing you to define custom sorting criteria....

Method 2: Spread Operator

This method involves creating a copy of the array using the spread operator (…) and then using array methods like sort. This approach keeps the original array unchanged and produces a new sorted array....

Method 3: Custom Sorting Function

We can define a custom sorting function based on our specific criteria and use it with the sort method. This method is useful when sorting complex data structures or when a custom sorting logic is required....

Method 4: Using a Priority Queue for Custom Sort Order

For more complex sorting scenarios, especially when dealing with prioritized sorting where certain elements need to be pushed to the front or back based on custom logic, a Priority Queue can be a useful data structure. In TypeScript, we can implement a Priority Queue using a class where the sorting logic is encapsulated in its functionality. This method is particularly useful when you have a large dataset and need an efficient way to maintain sorted order as elements are added or removed....
