I’ve seen both obj.prop and obj["prop"] used to access properties in JavaScript objects. Are there specific scenarios where one method is better than the other?

@xtt28Feb 03.2024 — Dot notation should be used when the property's name is both static (known before runtime) and a valid JavaScript identifier.

On the other hand, bracket notation should be used when the property's name is dynamic (known at runtime) or not a valid JavaScript identifier.
