What problems does Context solve compared to prop drilling?

Prop drilling happens when you pass props down multiple layers of components just to get data to a deeply nested child. This leads to:

  • Repetitive and bloated code.
  • Components getting props they don't really use — just passing them along.
  • Harder maintenance when app grows.

Context API solves this by:

  • Making the data globally available to any component.
  • Reducing dependency chains — a deeply nested component can directly access the data without intermediate components knowing about it.
  • Cleaner, more maintainable code.
