Of course, Web Components may replace React when there is enough support for all of these development needs, but I'm certain by then Web Components won't be what we know today.Just like React, it will have supporting libraries and even visual builders to allow developers to build applications easier. Web Components are a set of standards that make it possible to build new HTML element types - Custom Elements like <material-card> or <tab-bar>. Preact fully supports these standards, allowing seamless use of Custom Element lifecycles, properties and events. Preact is designed to render both full applications and individual parts of a page.
