En guise de solution de contournement, vous pouvez retourner un zéro dans la branche else - peu importe si vous n'utilisez pas la valeur de retour, mais simplement en raccourcissant (ou en essayant de raccourcir) l'opération. Now lets move on to some more complex examples.In this example, we’re coding for a movie theater.

If the condition is true, the ternary operator returns expression_1, otherwise it returns the expression_2. Using multiple ternary operators is not a good idea, better to use a function and put if-else conditions inside that and call that function from render. But what if I told you we could do the same exact thing in just one line of code? Ternary Operator: As the name indicates ternary operators take three operands. See the following example:In this example, the returned value of the ternary operator is the last value in the comma-separated list.In this case, you can simplify it by using a Boolean expression as follows:The following example shows how to use two ternary operators in the same expression:It is a best practice to use the ternary operator when it makes the code easier to read. : operator. : in this tutorial, you will learn how to use the JavaScript ternary operator to make your code more concise.
