In this lesson, we will\u00a0learn how to use conditional operators without using If and Else. Conditional\u00a0operators\u00a0let JavaScript\u00a0program executes certain jobs according to certain conditions.<\/p>\n

The syntax of the conditional operator is<\/p>\n

Conditional\u00a0Expression ? Execution 1: Execution 2<\/strong><\/p>\n

The conditional operator comprises three parts, the first part is the conditional expression, the second part is execution 1 and the last part is execution 2. The question mark ? separates the conditional expression and execution 1 whilst the colon: separates execution 1 and execution 2. If the conditional expression is true, then JavaScript will run execution 1 and ignores execution2. However, if the conditional expression is false, then JavaScript will ignore execution 1 and run execution 2. Therefore, the symbol ? and : completely replace If and Else.
