Common Contexts
You will frequently hear "もちろん" in everyday conversation when confirming plans, abilities, or knowledge. It adds a polite but confident tone.

Register and Nuance
"もちろん" is neutral and polite enough for most situations, including formal ones. It is less casual than some slang but very common in spoken and written Japanese.
Common Mistakes
Learners sometimes overuse "もちろん" in contexts where a softer or less assertive expression would be better. Remember it implies strong certainty, so use it when you want to emphasize that something is obvious or guaranteed.
