How to Access Array Elements using Index in TypeScript ?

Answer

To access array elements in TypeScript using index, you can use square brackets notation.

✐ Examples

1 Accessing Element at Index

In this example,

We create an array named numbers with integer values.
We access the element at index 2 using indexing numbers[1].
We print the accessed element.

TypeScript Program

let numbers: number[] = [1, 2, 3, 4, 5];
console.log(numbers[1]);

Output

2 Accessing Element at Index in a Loop

In this example,

We create an array named fruits with string values.
We iterate through the array using a for loop.
For each index, we access and print the element.

TypeScript Program

let fruits: string[] = ['Apple', 'Banana', 'Orange'];
for (let i = 0; i < fruits.length; i++) {
    console.log(fruits[i]);
}

Output

Apple
Banana
Orange
