In this lesson, we will see what a ternary operator does and how we can use it in our code.
We'll cover the following...

The ?: operator works very similarly to an if-else statement:
if (/* condition check */) {
/* ... expression(s) to execute if true */

/* ... expression(s) to execute if false */
