When working with JavaScript, you may come across situations where you need to write complex ternary operations with multiple conditions. Ternary operations are concise alternatives to if-else statements and can make your code more readable and easier to maintain.
In this blog post, we will explore how to write complex ternary operations with multiple conditions in JavaScript.

Basic Ternary Operator
The basic ternary operator in JavaScript has the following format:
(condition) ? expression1 : expression2;
Here, if the condition evaluates to true, the expression1 is executed, otherwise, the expression2 is executed.
To write a complex ternary operation with multiple conditions, you can chain multiple ternary operators together. For example:
let result = (condition1) ? expression1 : (condition2) ? expression2 : (condition3) ? expression3 : expression4;
In this example, if condition1 is true, then expression1 will be executed. If condition1 is false and condition2 is true, then expression2 will be executed. And so on.
Nested Ternary Operations
In some cases, you might need to have complex nested conditions. You can achieve this by nesting ternary operators inside each other. For example:
let result = (condition1) ? (condition2) ? expression1 : expression2 : expression3;
In this example, if condition1 is true, it checks condition2. If condition2 is true, expression1 is executed, otherwise expression2 is executed. If condition1 is false, expression3 is executed.
Using Logical Operators
You can also combine ternary operations with logical operators (&& and ||) to create more advanced conditionals. For example:
let result = (condition1 && condition2) ? expression1 : (condition2 || condition3) ? expression2 : expression3;
In this example, if both condition1 and condition2 are true, expression1 is executed. If condition2 or condition3 is true, expression2 is executed, otherwise expression3 is executed.
Conclusion
Writing complex ternary operations with multiple conditions in JavaScript can help you write more concise and readable code. By chaining ternary operators, nesting them, and combining them with logical operators, you can handle different conditions efficiently.
Remember to use these techniques sparingly and only when they enhance the readability and maintainability of your code.
