Hello:)
You have to initialize i. At the moment in your code is not an exiting variable. You can do it with let, const, var.
Second, to iterate through you need the length of the array.
Third, the value of your variable(i) should reach the length, so it should be smaller.

An example:

const cars = ["BMW", "Volvo", "Saab", "Ford", "Fiat", "Audi"];


for (let i = 0; i < cars.length; i++) {
}
