🤝 Combining Arrays

You can merge arrays with the + operator or the concat method. The + operator returns a new array, while concat modifies the original one.

a = [1, 2]
b = [3, 4]

# Non-destructive
c = a + b   # => [1,2,3,4], a unchanged

# Destructive
a.concat(b) # => [1,2,3,4], a is now modified
