This is the second version of the ternary operator tutorial. Done in high definition (which youtube accepts but revver doesn't) hence its been rescaled. Anyway it covers the ternary operator also known as the conditional operator. It operates on primitive and types. This makes it the most complex of all the operators since the resulting type depends on the type of the two main operands.
