Vue vs React: Programming Styles, View Syntax, Components, Routing, State Management, Reactivity and Lifecycle Comparison

The article offers a detailed technical comparison of the two major front‑end frameworks, Vue and React, examining how they differ in programming style, view syntax, component architecture, routing, state management, basic features, reactivity, lifecycle hooks and side‑effect handling.

Programming style : Vue relies on concise directives and template syntax (e.g., <input v-model="username"/> ), while React uses explicit JavaScript and JSX (e.g., <input value={username} onChange={e => setUsername(e.target.value)}/> ). Event handling also differs: Vue can call a method directly in @click , whereas React often requires a higher‑order function to pass parameters.

<input v-model="username"/>

<input value={username} onChange={e => setUsername(e.target.value)}/>

View style : Vue templates are written inside <template> blocks that resemble plain HTML, while React uses JSX which is JavaScript‑based and requires camel‑cased attributes and explicit closing tags. Conditional rendering examples illustrate the flexibility of JSX compared with Vue's template directives.

<template>
  <h1 v-if="level === 1">Title 1</h1>
  <h2 v-if="level === 2">Title 2</h2>
</template>

let App = () => {
  const level = 1;
  const Tag = 'h' + level;
  return (
    <div>{<Tag>Title {level}</Tag>}</div>
  );
};

Component style : Vue 2 uses the Options API with this , which can be less flexible; Vue 3 introduces the Composition API that avoids this and encourages function‑based logic. React before version 16.8 relied on class components (with this ), while newer versions favor function components and hooks, mirroring Vue 3's composition approach.

<template>
  <div class="my-component">
