In SharePoint Online, you can user Compare block helpers to render data based on the condition. Here are the examples

{{#compare pageContext.web.language '==' 1033}}
    <h1>This is rendered if current language is 1033</h1>
{{else}}
    <h1>This is rendered if current language is anything else
{{/compare}}

In this sample, based on the language , the SharePoint content will be rendered. This is really a nice feature to do dynamic rendering at most of the modern web parts in SharePoint online.

Happy SharePointing Folks 🙂
