Text Interpolation

Any {expr} in text is evaluated as JavaScript and HTML-escaped by default (XSS-safe).

Component.html

<p>Hello {state.user.name}</p>
<p>Total: {state.items.length} items</p>
<p>{state.count > 0 ? 'positive' : 'zero'}</p>

null / undefined render as an empty string.
To render unescaped HTML, see Raw HTML.
There is no escape for a literal { in text — any {…} is treated as interpolation. Use {String.fromCharCode(123)} or a const holding "{".
