1. Keep it Simple and Clear

One of the main advantages of ternary operations is their conciseness. However, it’s important to strike a balance between brevity and readability. Avoid using complex expressions or nesting multiple ternary operations, as this can make your code harder to understand. It’s best to use ternaries for simple and straightforward conditions.

2. Use Parentheses for Clarity

To avoid any ambiguity, it’s recommended to use parentheses to group the conditions and separate the different parts of the ternary operation. This will make your code more explicit and easier to comprehend at a glance. Here’s an example:

const result = (condition) ? trueValue : falseValue;

3. Consider Readability

While ternary operations can make your code concise, it’s crucial to prioritize readability. If the condition or the resulting values are too long, it might be better to use a traditional if-else statement instead. Remember, code should be readable and maintainable by others.

4. Avoid Complex Logic

Ternary operations are excellent for simple conditions, but they can quickly become convoluted if the logic is too complex. If your code requires multiple conditions or additional computations, it is advisable to use if-else statements or separate the logic into individual functions for better maintainability.

5. Comment Your Code

When using ternary operations, it’s always a good idea to add comments to explain the logic, especially if the condition or result is not immediately apparent. Clear comments help other developers understand the code more easily and can prevent misunderstandings or potential bugs in the future.

In conclusion, ternary operations are a powerful and concise way to make decisions in JavaScript. By following these best practices, you can use ternary operations effectively without sacrificing readability or maintainability. Remember to keep your conditions simple, use parentheses for clarity, prioritize readability, avoid complex logic, and add comments where necessary.
