How to Iterate Over an Array in TypeScript - Step by Step Examples

How to Iterate Over an Array in TypeScript ?

To iterate over an array in TypeScript, you can use a for loop or array methods like forEach or map.

In this example,

We create an integer array named numbers with some values.
We use a for loop to iterate over each element of the array and print the elements.

const numbers: number[] = [1, 2, 3, 4, 5];
for (let i = 0; i < numbers.length; i++) {
    console.log(numbers[i]);
}

In this example,

We create a string array named names with some strings.
We use the forEach method to iterate over each element of the array and print the elements.

const names: string[] = ['Alice', 'Bob', 'Charlie'];
names.forEach(name => console.log(name));

Alice
Bob
Charlie
