Is everything same as vue 2019 or changed? If there is changes how we will got that?
Vue 3 will be released. It will be faster because it can use functions only available in newer browsers (Internet Explorer will not get these) and also will it have smarter reactivity which can update components with less checking of changed state. Vue 3 will also gain an alternative way of writing components called composition API. It has a lot of advantages then grouping functionality inside components and also better type interference (will work better with typescript for example)
