Iterating

react

// React.js  (.jsx)
const array = [1, 2, 3, 4];
const Iteration = ({ items }) => <div> {items.map(item => <span>{item}</span>)} </div>;
ReactDOM.render(<Iteration items={array}/>, document.getElementById('array'));
<!-- React.js (html) -->
<div id="array"></div>

Vue

// Vue.js (js)
var Iteration = new Vue({
  el: '#array',
  data: {
    array: [1,2,3,4]
  }
});
<!-- Vue.js (html) -->
<div id="array">
  <span v-for="value in array">{{value}}</span>
</div>

props

react

// React.js (jsx)
const Component = ({ object }) => <span>{object.title}</span>
// Rendering the Component with the Prop
    // ...
    this.state.array.map( object => <Component key={object.id} object={object} />
    // ...

vue

// Vue.js (js)
var Component = Vue.component('component', {
  template: '<span>{{object.title}}</span>',
  props: {
    object: Object
  }
});
<!-- Vue.js (html) -->
<component
  v-for="object in array"
  track-by="id"
  :object="object">
</component>

two-way binding

react

/ React.js (jsx)
var Message = React.createClass({
  getInitialState() {
    return {
      message: ''
    }
  },
  handleMessageChange(e) {
    this.setState({message: e.target.value});
  },
  render() {
    return (
      <div>
        <input type="text" onChange={this.handleMessageChange} />
        <span>{this.state.message}</span>
      </div>
    )
  }
});

vue

// Vue.js (js)
var Message = new Vue({
  el: '#message',
  data: {
    message: ''
  }
});
<!-- Vue.js (html) -->
<div id="message">
  <input type="text" v-model="message" />
  <span>{{message}}</span>
</div>

Conditional Rendering

react

// React.js (jsx)
  render() {
    if ( this.state.loggedIn ) {
      return( <Component /> );
    } else {
      return( <LoginForm /> );
    }
  }

vue

<!-- Vue.js (html) -->
<component v-if="loggedIn"></component>
<login-form v-else></login-form>
