Sometimes, we want to use a for loop in multidimensional JavaScript array.
In this article, we’ll look at how to use a for loop in multidimensional JavaScript array.
How to use a for loop in multidimensional JavaScript array?
To use a for loop in multidimensional JavaScript array, we use a for-of loop.
For instance, we write
const arr = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9, 10],
];
for (const i of arr) {
for (const j of i) {
console.log(j);
}
}
to use a nested for-of loop to loop through the elements.
We loop through the outer array with the outer loop.
Then we loop through the elements in each nested array with the inner loop.
i
is the entry in the outer array being looped through.
j
has the value of each entry in the nested array.
Conclusion
To use a for loop in multidimensional JavaScript array, we use a for-of loop.
