How do I use constants in my code effectively?
Using constants helps improve code readability and maintainability. You can define constants using keywords like 'const' in JavaScript or 'final' in Java.
Can you give me an example in JavaScript?
Sure! You can define a constant like this: const MAX_USERS = 100;
Then, you can use MAX_USERS
throughout your code instead of hardcoding the value.
What are the benefits of using constants?
Constants prevent accidental changes to values, make your code easier to understand, and help avoid magic numbers.
Are there any best practices for naming constants?
Yes! It's common to use uppercase letters with underscores for constants, like MAX_CONNECTIONS
, to distinguish them from variables.
