Example p301

This first example of Vue shows that the mustache notation {{ property }} runs JavaScript expressions. When we mount a Vue application on the DOM element #template, Vue takes the content of the element as a template and replace those {{ property }} with values.

Try the following

• check that the JavaScript expressions in the placeholders in this example runs once and only once when this web page is loaded.
• Note: the next example will show reactivity: Vue will re-render the template when some data changes.
