Exciting React Features in 2023: A Look into the Future of Web Development

And now it’s Vue time!

Vue.js 3, also known simply as Vue 3, is a popular open-source JavaScript framework for building user interfaces. It is an evolution of Vue.js 2, with several significant improvements and new features. Evan You created Vue.js, and it has gained a strong following in the web development community due to its simplicity and flexibility.

Overall, Vue 3 builds upon the strengths of Vue 2 while addressing some of its limitations and providing developers with a more powerful and efficient framework for building web applications. It’s designed to be approachable for beginners yet scalable and flexible for building complex applications.

Let me describe some exciting features that have made their way into Vue 3 and code examples to demonstrate their usage.

Composition API

Vue 3 introduces the Composition API, a new way of organizing and reusing code in Vue components. It provides more flexibility and control over component logic, making sharing and composing functionality across components easier.

Let’s see this functionality in action in several examples:

<template>
  <div>
    <button @click="increment">Increment</button>
    <p>Count: {{ count }}</p>
  </div>
</template>

<script>
import { ref } from 'vue';
export default {
  setup() {
    const count = ref(0);
    const increment = () => {
      count.value++;
    };
    return {
      count,
      increment,
    };
  },
};
</script>

Creative time!
