The ternary conditional operator is a shorter version of an if
expression. It allows us to execute an expression if a condition is true, and another expression if the condition is false.
Here is the syntax:
`condition` ? `value if true` : `value if false`
Example:
let num1 = 1
let num2 = 2
let smallerNumber = num1 < num2 ? num1 : num2
// smallerNumber == 1
The syntax is shorter than an if
statement, and sometimes it might make more sense to use it.
