How To Write Multiple Statements In Ternary Operator In Javascript

In the realm of JavaScript programming, the ternary operator provides a concise way to write conditional statements. However, many developers are unaware of its potential for handling multiple statements effectively. In this article, we will delve into the intricacies of writing multiple statements within a ternary operator, offering step-by-step guidance and detailed examples.

Understanding the Ternary Operator

Before we explore the advanced usage of the ternary operator, let’s revisit its basic syntax:

condition ? expression1 : expression2;

Here, condition is evaluated, and if it resolves to true, expression1 is executed; otherwise, expression2 is executed.

Writing Multiple Statements

To incorporate multiple statements within a ternary operator, we can leverage JavaScript’s ability to use block statements with curly braces. By encapsulating the statements within curly braces, we can execute a sequence of actions based on the condition.

condition ? 
  (statement1, statement2, statement3) :
  (statement4, statement5);

In the above example, if condition is true, statement1, statement2, and statement3 will be executed in sequence. Conversely, if condition is false, statement4 and statement5 will be executed.

Step-by-Step Explanation

Let’s break down the process of writing multiple statements in a ternary operator:

1. Evaluate the Condition: Begin by evaluating the condition specified before the ?.
2. Use Curly Braces: Enclose the multiple statements you wish to execute within curly braces.
3. Separate Statements with Commas: Separate each statement within the curly braces using commas.
4. Execute Based on Condition: Depending on whether the condition is true or false, the corresponding block of statements will be executed.

Example Code Snippets

Example 1: Basic Implementation

const result = (condition) ? 
  (
    statement1(),
    statement2()
  ) :
  (
    statement3(),
    statement4()
  );

In this example, statement1 and statement2 will be executed if the condition is true; otherwise, statement3 and statement4 will be executed.

Example 2: Handling Variables

const message = (isSuccess) ? 
  (
    successMessage = "Operation successful",
    showSuccessPopup()
  ) :
  (
    errorMessage = "Operation failed",
    showErrorPopup()
  );

Here, based on the value of isSuccess, different variables are assigned and corresponding functions are called.

Conclusion

Mastering the art of writing multiple statements within a ternary operator can significantly enhance your JavaScript coding efficiency. By following the provided guidelines and examples, you can effectively utilize this feature to streamline your code and improve readability.
