What changed Vue 3?

Vuex is a state management pattern + library for Vue. js applications . It serves as a centralized store for all the components in an application, with rules ensuring that the state can only be mutated in a predictable fashion.

Vue 3.0, codename One Piece, was announced 2 years ago and was officially released in September 2020 . Vue 3 is a complete rewrite of the framework.

Other changes in Vue 3: Virtual DOM rewrite for better performance and improved TypeScript support . Native portals – now called Teleport. Fragments (virtual elements that won’t be rendered in the DOM tree) More flexibility for global mounting.
