📝 Usage Notes
while; before~
📖 How to use it
Expresses doing something during a period or before a state changes.
Attaches to
Attach to the dictionary form (non-past) of verbs, the ない-form (without ない) for negative verbs, or the ている form. Also attaches to nouns with の (e.g., 子供のうちに), and to い-adjectives and な-adjective stems with な (e.g., 若いうちに, 元気なうちに).
うちに means 'while' or 'before'. It sets a time frame: do something during that time before it ends. With dictionary form verbs, it often implies 'before it's too late' or 'while the chance exists'. With ている form, it describes doing something during an ongoing state. With negative verbs, it means 'while it is still not the case', like 'before it becomes...'

Asa no uchi ni shukudai o owaraseta.

若いうちにたくさん旅行したい。

Not 間に (aida ni)
間に also means 'while', but it emphasizes a duration, and the action can be continuous or punctual. うちに often implies 'before a change' and is used with states or negative forms. 間に can follow nouns and verbs, while うちに can follow nouns, adjectives, and verbs in certain forms.
