Comparative Analysis of React.js and Vue.js Technologies
Abstract
The selection of JavaScript-based libraries and frameworks for modern web application development has a direct impact on software performance, scalability, and long-term maintainability. This paper presents a comparative analysis of React.js and Vue.js, two widely used technologies in front-end development. The aim of the study is to evaluate these two approaches not only in terms of syntax and popularity but also with respect to architectural principles, component model, reactivity mechanisms, Virtual DOM implementation, performance, server-side rendering (SSR), ecosystem maturity, tooling support, and long-term maintainability. The research is based on a comparative analysis of the official technical documentation for React.js and Vue.js, as well as scholarly publications indexed in the Scopus and Web of Science databases. The findings indicate that React.js stands out due to its extensive ecosystem, architectural flexibility, and suitability for complex, largescale applications. In contrast, Vue.js offers an integrated reactivity system, a gentler learning curve, comprehensive official tooling, and lower initial complexity, making it an effective solution for smalland medium-sized projects. The study concludes that the choice between React.js and Vue.js should be determined by the project's scale, functional requirements, the development team's technical expertise, and the product's long-term development strategy.
