>> React is a library, not a framework They say it often but it's not true. React forces you into an entire workflow with JSX, bundling, source mapping, babel transpilation and often restricts you to using components that are designed specifically for React; accessing the raw DOM is nasty business. If it was a library, it would not hijack the DOM and override it with its own; that fact alone is more than enough to call it a framework. Any tool which takes over the execution environment is a framework by definition. A library is something you use, a framework is something you work inside. You could argue that react could be used to target only specific components but this would be missing the point that 99.9% of the time, React is not used like this; as soon as you have a hierarchy of components, it's a framework, not a library.
