Why we use Web Components?
1. We can use the same component with any JavaScript
Libraries

3. Micro Frontends
Micro Frontends? • Be Technology Agnostic • Isolate Team Code
• Establish Team Prefixes • Favor Native Browser Features over Custom APIs • Build a Resilient Site
Think about a web app as a composition of features
Functions Normal Frontend
Function1 Micro Frontend Function2 Function4 Function3

The biggest change that can be assumed = Framework migration
When Vue.js die, we should think about this
Why didn't we use Web Components earlier...?

None
Replacing UI implementation with Web Components, we can respond flexibly
to changing frameworks

What will become of us?
Vue.js is replaced by Web Components?
/P
Vue.js (and other frameworks) will be coexistent with Web Components
Web Components Vue.js (and other frameworks) Web Components Web Components
Web Components is "to encapsulate HTML elements"
Vue.js is "To make Web Applications"
