# Accessing arrays in loops

Hello everybody,

I’m currently learning loops, and this part got me puzzled :

``````const vacationSpots = ['Bali', 'Paris', 'Tulum'];

for (let i = 0; i < vacationSpots.length; i++ ){
console.log('I would love to visit ' + vacationSpots[i]);
}
``````

I don’t get how the “let i = 0” has to mean the 0 indexed in my array written earlier. (I’m sorry if I don’t make myself very clear, english is not my first language and when it gets technical its hard ahah)

Like why not use let i = [0] or let i = vacationSpots[0] ? How does the loop knows to pick the 0 as an index from an array and not as 0 being a number ?
And why doest it has to be vacationSpots[i] to log it and not just i ? (i being a variable I should be able to call it without the array no ? )

Thank you very much

Hello!
The `i` variable does not refer to anything within the array `vacationSpots`. Rather, it is just assigned a number (starting at `0`), which is incremented every time the loop loops. As you will have learnt in the previous lessons, `vacationSpots[i]` is an example of array indexing. Where, in this case, `i` is the index.

Thank you, it’s a bit more clear.
I’m just not sure how 0 refers to the array ? Maybe I’m thinking about this the wrong way, but since the loop concerns the array, it needs to be linked to it in some way no ?

The reason `i` starts at `0` is due to the declaration here:

This means `i` is now equal to `0`.

This tells the loop to run as long as this condition is met. In this case, the condition is that `i` must be less than the length of the `vacation Spots` array.

This tells the loop what to do with the variable `i`. This means `add one to i every time the loop loops`.

The only way it is “linked” to the array is in the condition

And when you print out each value from the array:

``````console.log('I would love to visit ' + vacationSpots[i]);
^^^^^^^^^^^^^^^^^
``````

`0` does not refer to the array, it is just a number. But, when you use array indexing-here:

the `0` refers to the first element in the `vacationSpots` array

Ok I think I get it, thank you very much for breaking down all the explanation
