3. Overview of Vue.js:
Vue.js, commonly referred to as Vue, is a progressive JavaScript framework designed for building user interfaces. Developed by Evan You, Vue prioritizes simplicity and ease of integration. It is often hailed for its flexible and approachable nature, making it an attractive choice for developers, both beginners and experienced alike. Key features of Vue.js include:
Reactivity System: Vue.js employs a reactive data-binding system that ensures automatic and efficient updates to the user interface whenever the underlying data changes.
Component-Based Architecture: Similar to React, Vue follows a component-based architecture where the UI is built as a collection of reusable components
Directives: Vue uses directives to add dynamic behavior to HTML elements in the template. Example: The v-if directive allows conditional rendering, and v-for is used for rendering lists.
Vue Router: Vue Router is the official routing library for Vue.js, providing tools for managing navigation in single-page applications.
Vuex (State Management): Vuex is the official state management library for Vue.js applications, providing a centralized state management solution.
Template Syntax: Vue uses a template syntax that closely resembles HTML, allowing developers to create dynamic and reactive templates declaratively.

Alibaba, Xiaomi, Adobe, Nintendo, Grammarly
4. Syntax and Templating:
React uses JSX, a JavaScript extension that allows HTML-like syntax within JavaScript files.
Vue.js uses an HTML-based template syntax for defining component templates.
Both React and Vue support dynamic content and data binding, but the syntax and directives used will differ.
Vue components are often structured with separate sections for template, script, and style, while React components are typically defined in a single file.
React and Vue.js use different approaches to define component templates and manage dynamic content. Let’s compare the syntax and templating languages used in React and Vue.js:
4.1. Component Structure:
React:
As discussed earlier React uses multiple components for single UI and each component is typically defined using JavaScript classes or functional components.
Class component:
class MyComponent extends React.Component {
render() {
return <div>Hello, React!</div>;
}
Functional Component:
return
}
Vue
In Vue js components are defined using a combination of template, script, and style sections in a single file. The template contains HTML, the script contains JavaScript, and the style contains CSS.
<template>
<div>Hello, Vue!</div>
</template>
<script>
export default {
// Component options go here
};
</script>
<style scoped>
/* Styles specific to this component */
</style>
4.2. Syntax
React: JSX(JavaScript XML)
JSX is a syntax extension for JavaScript that looks similar to XML or HTML. It allows developers to write UI components in a declarative and expressive manner.
return <div>Hello, React!</div>;
}
Vue: Template Syntax
Vue.js uses an HTML-based template syntax. Templates are defined in the template option of a component
<div>Hello, Vue!</div>
</template>
4.3. Dynamic Content:
React: Dynamic content and logic within JSX are written using JavaScript expressions enclosed in curly braces.
const message = “Hello, React”
return <div>{ message } </div>;
}
Vue: Data binding in Vue.js is achieved using double curly braces {{ }} for one-way binding and the v-bind directive for attribute binding.
<p>{{ message }}</p>
<a v-bind:href=“url”>Click me</a>
</template><script>
export default {
data() {
return {
message: ‘Hello, Vue!’,
url: ‘https://example.com’,
};
},
};
</script>
The choice between JSX in React and HTML-based templates in Vue.js often boils down to developer preference, team familiarity, and project requirements.
JSX provides a more integrated approach, allowing for seamless JavaScript integration, while Vue.js templates offer a simpler and more HTML-like syntax. Ultimately, both approaches have their strengths, and the decision often comes down to the specific needs and preferences of the development team.
5. Component Lifecycle:
React has 3 different phases of lifecycle which includes mounting, updating, and unmounting. Each phace includes different methods to execute different functions. Similarly Vue has 4 different phases named creation, mounting, updating and destruction.
React’s lifecycle methods are more explicit, giving developers fine-grained control over various phases.
Vue.js provides lifecycle hooks with a more declarative approach, separating creation, mounting, updating, and destruction phases.
Vue.js has additional hooks like beforeCreate, beforeMount, beforeUpdate, and beforeDestroy, allowing developers to perform actions just before certain phases.
6. State Management:
State management is a critical aspect of building complex applications, and both React and Vue provide solutions to handle state. In React, the widely used tool is Redux, while in Vue, Vuex is the dedicated state management library. Let’s compare state management in React with Redux and Vue with Vuex.
7. Centralized Store:
React uses a single centralized store that holds the entire application state. Here the state is read-only, and changes are made through dispatched actions. Reducers are used to specify how the state changes in response to actions. Connect function is used to link React components and Redux stores. These connected components receive state as props and can dispatch actions.
Now, Vue utilizes a centralized store similar to Redux, containing the entire application state. Here the State is modified through mutations committed by actions.
Vue components can use mapState and mapActions helpers to connect to the Vuex store. State and actions are available as computed properties and methods.
Both Redux and Vuex provide a centralized store, allowing for predictable state management in large applications. The syntax and concepts are similar, making it relatively easy for developers familiar with one to adapt to the other. Both libraries excel at managing state in a structured and maintainable way.
8. Routing:
React Router and Vue Router play a crucial role in enabling navigation and handling routing logic in single-page applications.
React Router uses a declarative approach for routing configuration whereas Vue utilizes a more imperative approach for routing configuration.
Routes are defined using the component and nested inside a or component in React. But in Vue routes are defined as an array of objects using the routes option in the router instance.
import { BrowserRouter as Router, Route} from ‘react-router-dom’;const App = () => {
return (
<Router>
<Route path=“/home” component={Home} />
<Route path=“/about” component={About} />
</Router>
);
};
import Vue from ‘vue’;
import VueRouter from ‘vue-router’;Vue.use(VueRouter);const router = new VueRouter({
routes: [
{ path: ‘/home’, component: Home },
{ path: ‘/about’, component: About },
],
});
Both React and Vue Support dynamic route parameters using the :param syntax.
// React Router dynamic route
<Route path=“/users/:id” component={UserDetail} />
In React navigation is achieved using the component for declarative links or programmatically using the history object. But navigation is achieved using the component for declarative links or programmatically using the $router object in Vue.
React has a large and active community with widespread adoption in the industry. It is maintained by Facebook and has contributors from various companies and individual developers. React’s official documentation is comprehensive, well-organized, and regularly updated. It covers the core concepts, API references, and guides for common use cases.
// React Router navigation
import { Link } from ‘react-router-dom’;
const Navigation = () => {
return (
<div>
<Link to=“/home”>Home</Link>
<Link to=“/about”>About</Link>
</div>
);
};
// Vue Router navigation
<template>
<div>
<router-link to=“/home”>Home</router-link>
<router-link to=“/about”>About</router-link>
</div>
</template>
9. Community support and documentation
The React team provides documentation for various tools and libraries in the React ecosystem, including React Router, Redux, and more. React’s ecosystem is extensive, with a wide range of third-party libraries, tools, and plugins. The community actively contributes to building and maintaining these resources. React has a strong presence on platforms like Stack Overflow, GitHub, Reddit, and Twitter. Developers can find support, share knowledge, and engage with the community on these platforms.
