How to Sort an Array in TypeScript - Step by Step Examples



How to Sort an Array in TypeScript ?

Answer

To sort an array in TypeScript, you can use the built-in sort() method.



✐ Examples

1 Sort Integer Array in Ascending Order

In this example,

  1. We create an integer array named numbers with values 5, 2, 8, 1, 6.
  2. We use the sort() method on the array to sort it in ascending order.
  3. The sort() method sorts the array elements in ascending order based on their UTF-16 code units values.
  4. Finally, we print the sorted array numbers to the console.

TypeScript Program

let numbers: number[] = [5, 2, 8, 1, 6];
numbers.sort((a, b) => a - b);
console.log("Sorted array in ascending order: ", numbers);

Output

Sorted array in ascending order:  [ 1, 2, 5, 6, 8 ]

2 Sort Integer Array in Descending Order

In this example,

  1. We create an integer array named numbers with values 5, 2, 8, 1, 6.
  2. We use the sort() method on the array with a custom comparator to sort it in descending order.
  3. The custom comparator sorts the array elements in descending order.
  4. Finally, we print the sorted array numbers to the console.

TypeScript Program

let numbers: number[] = [5, 2, 8, 1, 6];
numbers.sort((a, b) => b - a);
console.log("Sorted array in descending order: ", numbers);

Output

Sorted array in descending order:  [ 8, 6, 5, 2, 1 ]
