Arrays look like lists inside square brackets. Each value in the array should be separated out with commas.
Every time you create an array, you’ll need to store it into a variable right away so that you can access the values later. Because this is so important, the block to create an array automatically stores the array into a variable.
You can access a value inside your array by using its index number. The index numbers start from 0 and count up until they get to the end of the array. For example, in the above array, “a” is at index 0, “b” is at index 1, and “c” is at index 2.
