Every line, explained
let fruits = ["apple", "banana", "cherry"]- An array stores several values in one variable. The values go between square brackets, separated by commas.
print(fruits[0])- You get one item using its index (position) in square brackets, and counting starts at 0, not 1! fruits[0] is "apple", fruits[1] is "banana", fruits[2] is "cherry".
print(fruits.count)- .count tells you how many items the array holds: here, 3. (Swift says count, where some languages say length or len.)
