About ないうちに
In contrast to うちに, which is often used to express the 'optimal', or 'best' time within which something should occur, ないうちに expresses the time within which something 'does not' occur, and results in (or causes) something negative, or will cause something negative if not dealt with. This means that 'before (A) happens (B)', or 'without (A) happening, (B).
うちに will be paired with verbs in their ない (negative) form, before the (B) phrase highlights something that 'is done to prevent (A) from happening', or 'happened unfortunately during (A)'.
Fun Fact
前に and ないうちに are used in very similar situations, with the primary difference being that ないうちに focuses more on unfavorable results.
- 出かける前にバイオリンの練習をしないといけない。I need to practice playing my violin before I go out.
-
知らないうちに家の前にあるラーメン屋が潰れていた。Without realizing it, the ramen shop in front of my house went out of business.

Thank you for point these out to us! I have updated the related grammar section to include 前に and have added a note about it in the information section on the Meaning page. I have also removed the redundant resource listing and added the tanos link that you provided. Cheers!

HeyThat’s actually my error, I changed sentence to ひめる because it sounds more natural that way, but forgot to change the word for conjugation
It should be all good now.
Sorry for the inconvenience
