Can a nested array be divided into two separate arrays in Javascript?

I have received an array structured like this

var cars = [['BMW'],[],['6000cc']];

This array includes two distinct values of the same item. The presence of an empty array indicates a change in data. The data on the left side of the empty array corresponds to one set of information, while the data on the right side corresponds to another set.

My task is to divide this array into two separate arrays.

Answer №1

To separate an array into two parts with an empty array as the separator, the first step is to locate the index of the empty array.

var cars = [['BMW'],[],['6000cc']];
var index = -1
for(var i=0;i<cars.length;i++){
if(cars[i].length === 0)
{
index = i;
break;
}
}

After finding the index, use the slice method to split the array:

var arr1 = cars.slice(0, index);
var arr2 = cars.slice(index+1);

Answer №2

One way to organize and manipulate arrays in ES6 is by utilizing Array De-structuring alongside the split method.

let vehicles = [['Toyota'],['Honda','Hyundai'],['Ford']];
let [v1, v2, v3] = vehicles;
console.log(v1, v3);
