I’ve been working with React for a while and it feels great early on, but I’m curious what actually becomes difficult once applications grow and multiple people are working on them.

A few pain points I keep hearing about:

• state management getting messy over time
• prop drilling / context overuse
• component reusability becoming harder than expected
• performance/debugging issues in larger apps

For developers maintaining React apps in production:

• what has been your biggest long-term pain point?
• was it architecture, state, performance, testing, or team scaling?
• anything you wish you had standardized earlier?

Would love to hear real experiences from people working on larger React codebases.
