Why people aren’t switching to Svelte yet

Svelte is a lightweight, component-based JavaScript framework that compiles code into efficient vanilla JavaScript, offering an alternative to the virtual DOM diffing technique used by frameworks like React. Despite its growing popularity since its release in 2016 and having over 39,000 stars on GitHub, Svelte's adoption remains limited, with only about 6,000 websites using it compared to millions for React, Vue, and Angular. Factors contributing to its slower adoption include late TypeScript support, the lack of an official CLI for project scaffolding, a smaller community, and less package support, which can lead to increased development effort for certain features. Additionally, Svelte lacks the backing of major tech companies, which influences its perceived maturity and reliability in the industry, thereby affecting its demand among developers and employers. Nonetheless, Svelte is viewed as a significant part of the future of web development, with potential for broader adoption should these challenges be addressed.
