Vue Template Syntax

What is Template Syntax?

Vue template syntax allows you to bind data to the DOM using HTML-based templates with special directives and expressions.

Text Interpolation

<p>{{ message }}</p>

Double curly braces {{ }} are used to display dynamic data.

Directives

Directives are special attributes prefixed with v- that apply reactive behavior to the DOM.
