Vue.js Models

In Vue.js, models are used to bind data to form inputs and update the data when the input changes. This allows for two-way data binding between the view and the model.

Here’s an example of how to use a model in Vue.js:

<template>
  <div>
    <input v-model="message" type="text">
    <p>{{ message }}</p>
  </div>
</template>

<script>
export default {
  data() {
    return {
      message: ''
    }
  }
}
</script>

In this example, we have an input element with the v-model directive bound to the message data property. This means that any changes to the input value will automatically update the message property, and vice versa. The {{ message }} expression is used to display the current value of the message property in a paragraph element.

So, when the user types something into the input field, the message property is updated, and the paragraph element is updated to display the new value of message. This is all thanks to the two-way data binding provided by the v-model directive.
