  • The ternary operator is a conditional operator that evaluates three expressions and returns one of them depending on the condition.
  • The ternary operator is often used to assign a value to a variable. For example,
  • x = x > 20 ? "greater" : "lesser"

There are many advantages of using the ternary operator in Ruby. It can reduce code complexity, make it easier for programmers to read and understand what's going on, and it can also help improve performance in some cases.

The syntax for using the ternary operator in Ruby is as follows:

  • # ?:
  • a = 10
  • b = 20
  • c = a + b > 30 ? "Yes" : "No"
  • # Yes

The conditional (ternary) operator is the only one in JavaScript that takes three operands: a condition followed by a question mark (? ), an expression to execute if the condition is truey followed by a colon (:), and lastly an expression to execute if the condition is false.

?: is a ternary operator in computer programming that appears in several programming languages as part of the syntax for basic conditional expressions. The conditional operator is also known as the inline if (iif) or ternary if. If the value of an is true, the equation a? b: c evaluates to b, and otherwise to c.
