LU05a - VUE Directives

1. I can explain what Vue Directives are.
2. I can explain what Vue Directives are used for.
3. I can name and explain at least four types of directives.
4. I can use VUE directives as an example.

Vue directives are special tokens in Vue.js that extend the functionality of HTML by providing dynamic behavior to DOM elements. They are prefixed with v- and are used to bind data, manipulate DOM attributes, or listen to events. Common directives include v-bind for binding attributes, v-if for conditional rendering, and v-for for looping over data. By leveraging directives, developers can create highly interactive and reactive user interfaces with minimal effort.

1. Reactivity: Automatically update the DOM when the underlying data changes.

2. Extensibility: You can create custom directives for advanced behavior.

3. Simplicity: Integrate seamlessly into templates for common tasks like event handling or conditional rendering.

1. v-if: Conditionally renders an element or removes it from the DOM based on the truthiness of an expression.
2. v-for: Iterates over a list or object, generating a new element for each item in the collection.
3. v-bind: Dynamically binds an attribute (e.g., `src`, `class`, `style`) to an expression, allowing for reactive updates.
4. v-model: Creates a two-way binding between a form input or component and a Vue instance's data property.
