Vue.js Overview
1. Introduction to Vue.js
What is Vue.js: Vue.js is a progressive JavaScript framework used for building user interfaces and
single-page applications (SPAs).
History of Vue.js: Vue.js was created by Evan You in 2014 and has gained popularity due to its
simplicity and ease of integration with other libraries and projects.
Key Features: Vue.js offers a reactive data-binding system, component-based architecture, and a
flexible ecosystem for building modern web applications.
2. Vue.js Components
Component System: Vue.js applications are built using reusable components, where each
component encapsulates its own template, logic, and styles.
Single-File Components (SFCs): Vue supports single-file components, where the template, script,
and styles are written in the same file with a .vue extension.
Component Lifecycle: Vue components have a lifecycle with hooks like created, mounted, updated,
and destroyed, allowing developers to run code at specific stages.
3. Vue.js Directives
v-bind: The v-bind directive is used for dynamically binding attributes to HTML elements in a Vue
template.
v-if, v-show, v-else: These directives are used for conditional rendering of elements based on
reactive data.
v-for: The v-for directive is used to loop through data and render elements based on each item in the
data set.
4. Vue.js Data Binding
Two-Way Data Binding: Vue.js supports two-way data binding between form inputs and data
properties using the v-model directive.
Reactive Properties: Vue makes properties reactive, meaning changes to data are automatically
