Here is an example of how to go through an array of arrays using the each
function in JavaScript:
const arrOfArrs = [
[1, 2, 3],
[4, 5, 6],
[7, 8, 9]
];
arrOfArrs.forEach((arr) => {
arr.forEach((num) => {
console.log(num);
});
});
In this example, we have an array called arrOfArrs
which contains three arrays of numbers. We use the forEach
method to go through each array in arrOfArrs
, and then use another forEach
method to go through each number in the current sub-array. Finally, we log each number to the console.
This will output the numbers 1 through 9 in order.
