Pros and cons

What React does especially well — and the limits to anticipate.

Pros

Excellent documentation and huge community, easy to find support.
Declarative approach makes code readable and maintainable.
Excellent for complex applications and large-scale projects.

Cons

Steeper learning curve than Svelte or Preact for beginners.
Virtual DOM adds an abstraction layer and weight to the bundle.

React: when it makes sense.

React dominates the market and offers the richest ecosystem; choose it for complex projects where flexibility and community matter.
