Events and Modifiers</a></nav><main><p>The library tries to provide pure JavaScript tool(s) to create reactive interfaces.</p><p>We start with creating and modifying a static elements and end up with UI templates. <i>From <code>document.createElement</code> to <code>el</code>.</i> Then we go through the native events system and the way to include it declaratively in UI templates. <i>From <code>element.addEventListener</code> to <code>on</code>.</i></p><p>Next step is providing interactivity not only for our UI templates. We introduce signals (<code>S</code>) and how them incorporate to UI templates.</p><p>Now we will clarify how the signals are incorporated into our templates with regard to application performance. This is not the only reason the library uses <code>scope</code>s. We will look at how they work in components represented in JavaScript by functions.</p><!--<dde:mark type="component" name="example" host="this" ssr/>--><divid="code-1pn55"class="example"><!--<dde:mark type="component" name="code" host="parentElement
