How to Iterate over a Two Dimensional Array in TypeScript ?

Answer

To iterate over a Two Dimensional Array in TypeScript, you can use nested loops.

✐ Examples

1 Iterating over a 2D Array of Integers

In this example,

We declare and initialize a 2D array of integers named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

TypeScript Program

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

Output

2 Iterating over a 2D Array of Strings

In this example,

We declare and initialize a 2D array of strings named matrix.
We use nested loops to iterate over the rows and columns of the array.
Inside the inner loop, we access and print each element of the array.

TypeScript Program

const matrix: string[][] = [['Hello', 'World'], ['TypeScript', 'JavaScript']];
for (let i = 0; i < matrix.length; i++) {
    for (let j = 0; j < matrix[i].length; j++) {
        console.log(matrix[i][j]);
    }
}

Output

Hello
World
TypeScript
JavaScript
