- Solves low-level problems with as little magic and opinion as possible. - Is NOT a monolothic framework. Maintaining a large code base is just not practical. - Is less than 10kb minified and gzipped. - Focuses on extensibiity and granularity. Use as much or as little of it as you want. - Plays nice with other frameworks. Easily use side-by-side with ReactJS or Angular.
