How do I use constants in my code?

Using constants in your code helps to make it more readable and maintainable. You can define a constant using the const keyword in languages like JavaScript, or final in Java. Would you like an example?

Yes, please provide an example in JavaScript.

Sure! In JavaScript, you can define a constant like this: const PI = 3.14;. You can then use PI throughout your code without worrying about it changing.

What happens if I try to change a constant?

If you try to change a constant, you'll get a TypeError. For example, PI = 3.14159; will throw an error because PI is a constant.

Are there any best practices for using constants?

Yes! It's best to use uppercase letters for constant names, like MAX_USERS, to distinguish them from regular variables.
