Despite AI and the push for simplification in web development, JavaScript frameworks aren’t quite ready to yield their hold on the frontend.

The New Stack is a publication covering trends and technologies in cloud-native development, DevOps, and software delivery. Developers can learn about containerization, Kubernetes, and cloud computing, as well as explore topics such as microservices architecture, serverless computing, and continuous integration/continuous delivery (CI/CD) pipelines.

The New Stack

JavaScript in 2025 saw a shift toward performance optimization and web standards, with developers questioning React's dominance as modern browsers matured. Signals emerged as a key reactivity pattern across Angular, Vue, Solid, and Svelte. Compilers took on more optimization work, with React Compiler and Svelte 5's Runes automating performance improvements. VoidZero launched Vite+ as a unified Rust-based toolchain to address JavaScript's fragmentation. AI integration moved to the frontend through MCP servers and browser-based machine learning libraries, while new frameworks like Hono, Mastro, and Wasp addressed specific use cases from edge computing to multipage apps.
