TUTORIAL VUE 3 EPISODE 5 : INTERPOLATION

In this tutorial, we will explore the concept of interpolation in Vue 3. Interpolation is a powerful feature that allows us to bind data from our Vue instance to our HTML template. This is a fundamental concept in Vue and is essential for building dynamic and reactive applications.

What is Interpolation?

Interpolation in Vue is denoted by double curly braces {{}}. This syntax allows us to insert dynamic data within our HTML template. When the Vue instance is created, it automatically updates the HTML whenever the bound data changes.

Using Interpolation in Vue Components

Let’s take a look at a simple example of how to use interpolation in a Vue component. Suppose we have a Vue instance with the following data:

var app = new Vue({
  data: {
    message: 'Hello, Vue!'
  }
})

We can display the value of the message data property in our HTML template using interpolation:

<div id="app">
  {{ message }}
</div>

When the Vue instance is created, the value of message will be inserted into the HTML, resulting in “Hello, Vue!” being displayed on the page.

Dynamic Interpolation

Interpolation in Vue is not limited to just strings. We can also bind dynamic data such as variables, expressions, and even methods to our HTML template using interpolation. This allows us to build dynamic and reactive applications that respond to changes in our data.

Conclusion

Interpolation is a fundamental concept in Vue that allows us to bind data from our Vue instance to our HTML template. This powerful feature enables us to build dynamic and reactive applications that respond to changes in our data. By understanding and using interpolation, you can take advantage of Vue’s powerful reactivity system and build rich and interactive web applications.
