+= ?: Ternary Operator
+
+
+// OVERVIEW SECTION STARTS
+[#overview]

+
+[float]
+=== Description
+It takes three arguments rather than the typical one or two that most operators use. The first argument is a comparison argument, the second is the result upon a true comparison, and the third is the result upon a false comparison. It is an alternative to shorten an if-else block. It can help increase the readability and reduce the number of lines in your code.
