+# The broadcast operator (.) can be quite useful when dealing with arrays.
+# Basically whenever an operator or function is used, you can just write
+# a dot (.) before the operator/function to make it act elementwise.
+
+# Here we elementwise add 3 to the array
+a = [1, 2, 3, 4]
+a .+= 3
+@show a
+
+# Here we elementwise multiply a by 2 and then elementwise add a and b.
+b = a .* 2
+@show b
+c = a .+ b
+@show c
+
+# To elementwise use more general functions the dot symbol is placed between
+# the function name and parentheses.
+f(x) = 2x^2
+d = f.(c)
+@show d
