Creating Computed Properties with Vue’s Composition API

In this post, we will give you information about Creating Computed Properties with Vue’s Composition API. Here we will give you detail about Creating Computed Properties with Vue’s Composition API And how to use it also give you a demo for it if it is necessary.

To create a computed property with the Vue’s Composition API, you should call Vue’s computed() function.
For example, the following code demonstrates how to create a computed property that transforms a string value to a lowercase.

  setup() {
    const name = Vue.ref('World');
    const lowercase = Vue.computed(() => name.value.toLowerCase());

    // Make sure to return your computed property
    // so your templates can use it!
    return { name, lowercase };
  template: '
    <input v-model="name">
      Hello, {{lowercase}}

Below is a live example to Creating Computed Properties with Vue’s Composition API.
Notice that Vue automatically updates the value of lowercase whenever name changes.

Vue.js is a progressive JavaScript framework that makes building user interfaces simple and enjoyable. Vue is designed from the ground up to be incrementally adoptable, so you can use the features you need, and mix and match Vue with other libraries or frameworks.

Vue is a relatively new framework, but it has quickly become one of the most popular JavaScript frameworks in the world. It is used by large companies like Alibaba, Baidu, and Xiaomi, as well as by thousands of smaller businesses and startups.

Here are some of the features that make Vue.js so popular:

  • Declarative rendering: Vue uses a declarative rendering model, which means that you can describe the desired output of your application in terms of HTML, CSS, and JavaScript. This makes it easy to reason about your code and to make changes to your application.
  • Reactivity: Vue is a reactive framework, which means that it automatically updates the DOM whenever there is a change to the application’s state. This makes your application feel fast and responsive.
  • Composition: Vue is a component-based framework, which means that you can build your application out of reusable components. This makes your code more maintainable and easier to test.
  • Performance: Vue is a highly performant framework. It has been benchmarked against other popular JavaScript frameworks, and it has consistently outperformed them.
