Choosing a JavaScript tool
React is a library for building component-based interfaces. Vue and Svelte also organize interactive interfaces around components, while Angular supplies a more integrated application framework. jQuery is mainly useful when working with an existing site that already uses it or when simplifying DOM tasks.
Consider how much interaction the page needs, the team's familiarity with the tool, and the cost of adding it to the browser. A small widget may not need an application framework; a larger app benefits from a clear component and state-management approach.
