Vue.js
A progressive JavaScript framework for building UIs — lighter weight than React, widely used in European and Asian markets.
Vue.js is a popular alternative to React for building frontend applications, favored for its gentler learning curve and clean separation of HTML, JavaScript, and CSS in single-file components. It's commonly seen at mid-size companies, agencies, and organizations outside of the US tech ecosystem.
Typical time to job-readiness: ~2 months.
Learning Vue.js
Beginner
Learn Vue's Options API — components, directives (v-if, v-for, v-model), and reactive data. Build a simple CRUD interface to understand the data flow.
Intermediate
Transition to the Composition API with setup(), add Vue Router for navigation, and manage state with Pinia. Build a complete small application with multiple views.
Advanced
Understand Vue's reactivity internals, write custom directives and plugins, and gain Nuxt.js experience for server-side rendering. Vue expertise is often assessed through reviewing an existing codebase.

- Computed properties vs methods vs watchers
