What should developers avoid when building with Vanilla JavaScript in 2026?
Developers should avoid using Vanilla JavaScript for complex single-page applications where frameworks like React, Vue, or Svelte offer superior state management, component reuse, and testability. Steer clear of direct DOM manipulation for dynamic list rendering-these approaches do not scale well as complexity increases. Additionally, do not use Vanilla JS without TypeScript for projects with multiple contributors, as the absence of type safety significantly raises the risk of integration bugs and difficulties in refactoring.
