Frontend development isn't getting easier.
Modern applications now include:
AI features
Real-time collaboration
Massive data grids
Dashboards
Role-based permissions
Offline support
Analytics
Responsive layouts
As projects grow, so does frontend complexity.
Where complexity comes from
Most enterprise applications eventually struggle with:
duplicated components
inconsistent UI
state management
dependency sprawl
maintenance
onboarding new developers
None of these problems are caused by JavaScript itself—they're caused by application scale.
Why UI frameworks help
A mature JavaScript UI framework provides:
reusable components
predictable architecture
standardized patterns
better collaboration
consistent UX
Instead of solving the same UI problems repeatedly, developers build on proven foundations.
Component libraries vs complete frameworks
Many React projects combine:
Material UI
AG Grid
React Hook Form
TanStack
Chart.js
custom layouts
This works well for many applications.
However, enterprise software often benefits from a more integrated approach.
That's one reason frameworks like Ext JS remain relevant. Rather than assembling numerous third-party libraries, it provides enterprise-ready grids, charts, forms, dashboards, layouts, theming, and data handling in a single ecosystem.
It's not necessarily the right choice for every project, but for large internal systems, ERP software, CRM platforms, and operations dashboards, it can significantly reduce frontend complexity.
Final Thoughts
The best framework isn't always the most popular.
It's the one that helps your team deliver features faster while keeping the codebase maintainable over the next several years.
