How to Sort a String Array in Dictionary Order in TypeScript ?

Answer

To sort a string array in TypeScript in dictionary order, you can use the `sort()` method. To sort in descending order, you can use a custom compare function or reverse the array after sorting.

✐ Examples

1 Sort String Array Ascending

In this example,

We create a string array `words` with unsorted elements.
We use the `sort()` method without any parameters to sort the array in ascending dictionary order.
We print the sorted array.

TypeScript Program

const words: string[] = ["banana", "apple", "orange", "grape"];
words.sort();
console.log("Sorted Array Ascending:", words);

Output

Sorted Array Ascending: [ 'apple', 'banana', 'grape', 'orange' ]

2 Sort String Array Descending

In this example,

We create a string array `words` with unsorted elements.
We use a custom compare function to sort the array in descending dictionary order.
We print the sorted array.

TypeScript Program

const words: string[] = ["banana", "apple", "orange", "grape"];
words.sort((a, b) => b.localeCompare(a));
console.log("Sorted Array Descending:", words);

Output

Sorted Array Descending: [ 'orange', 'grape', 'banana', 'apple' ]
