When naming variables in JavaScript, it's important to be descriptive and use camelCase. For example, use 'userName' instead of 'username'.

CamelCase improves readability, especially in longer variable names, making it easier to distinguish between words.

Can you give me examples of bad variable names?

MagicBuddy
MagicBuddy

Sure! Bad variable names include single letters like 'x' or vague names like 'data' or 'temp' that don't convey meaning.

What about naming constants? Is there a different convention?

MagicBuddy
MagicBuddy

Yes! Constants are usually named using ALL_CAPS with underscores, like 'MAX_USERS' or 'API_URL'.
