Last time, we saw how arrays like let planets = ["Mercury", "Venus", "Earth"];

can hold multiple values together in order.

But how do we get just one specific item out of the array, like "Venus"?

Any ideas on how we might pinpoint an item?

Each item in an array has a specific position, called an index. Think of it like a numbered slot.

JavaScript starts numbering these positions from zero, not one! This is called zero-based indexing.

So, what index number do you think the first item in an array has?

That's right, the first item is at index 0. The second item is at index 1, the third at index 2, and so on.

To access an item, you use the array variable followed by the index in square brackets [].

If we have ["Mercury", "Venus", "Earth"], what value does planets[0] give?

Using our planets array: planets[0] gives , gives , etc.
