How To Iterate Over Items in Vue.js With V-for
In Vue.js, the v-for directive is used to render a list of items based on an array or object. In this tutorial, we will show you how to use v-for to iterate over items in Vue.js.
Keywords: Vue.js, v-for directive, array, object, iteration, rendering.
## Prerequisites
Before we get started, you should have a basic understanding of Vue.js and HTML. You should also have a code editor and a web browser installed on your computer.
## Step 1: Create an HTML file
Create a new HTML file and name it `index.html`. In the file, add the following code:
```html
Vue.js v-for Tutorial
```
In this code, we have created a basic HTML file with a title and a script tag that links to the Vue.js library. We have also added a `div` with an id of `app`, which will be used to render our Vue.js app. Inside the `div`, we have added a `ul` element with a `li` element that uses the `v-for` directive to iterate over items in the `items` array.
## Step 2: Create a Vue.js app
Create a new JavaScript file and name it `app.js`. In the file, add the following code:
```javascript
var app = new Vue({
el: '#app',
data: {
items: ['Item 1', 'Item 2', 'Item 3']
}
});
```
In this code, we have created a new Vue.js app and passed in an object with two properties: `el` and `data`. The `el` property specifies the element that the Vue.js app will be mounted to, which in this case is the `div` with an id of `app`. The `data` property specifies an object with an array called `items`.
## Step 3: View the app
Save both files and open `index.html` in your web browser. You should see a list of three items:
- Item 1
- Item 2
- Item 3
Congratulations! You have successfully used the v-for directive to iterate over items in Vue.js.
## Conclusion
In this tutorial, we showed you how to use the v-for directive to iterate over items in Vue.js. We hope you found this tutorial helpful and feel free to experiment with the code to see how it works.
