Which one do you prefer to use: Vanilla JS, React, or Vue? And what factors influence your choice?

The choice between Vanilla JS, React, and Vue mainly depends on the project requirements and the maturity of the development team. If the project is a small app or a static site and the team doesn’t have prior experience with specialized JS libraries, I always lean toward Vanilla JS. The reason is simple: no learning curve, easy short‑term maintenance, and its performance rivals any modern library in most scenarios. You write the code once and understand it completely without relying on a complex external architecture. Compatibility issues between libraries or versions are virtually eliminated. If the project is real‑world and complex—like a large e‑commerce platform or a demanding single‑page application with lots of interactions and constantly changing state—I don’t hesitate to pick React. The main reason is its efficient virtual DOM and massive ecosystem: Redux, Next.js, Webpack, Tailwind (easy to integrate). Even if the team needs some time to learn JSX and the update cycle, the payoff is worth it because debugging becomes more organized thanks to the component‑based structure, which makes debugging complex sites easier. That said, my current favorite is Vue.js, especially for medium‑size projects or small teams that need a flexible, fast‑to‑build approach without sacrificing efficiency. Vue gives you a high degree of control: the classic Options API, the newer Composition API, and progressive feature adoption. With Pinia or Vuex for state management, you get solid performance and rapid development speed. For example, I recently used Vue for a shopping site with dynamic filtering and real‑time cart updates: the final page size was under 200 KB and loading speed on mobile was excellent. My personal pick summary: 🔹 Vanilla JS: “When I want full control and no dependencies.” 🔹 React: “When the project is huge and I need a wide support system and long‑term sustainability.” 🔹 Vue: “When I want speed of implementation and flexibility with a small/medium team.”
