It is also possible to provide a&nbsp;some attribute(s) declaratively using <code>Object.assign()</code>. More precisely, this way you can sets some <a href="https://developer.mozilla.org/en-US/docs/Glossary/IDL" title="MDN page about Interface Description Language"><abbr title="Interface Description Language">IDL</abbr></a>.</p><!--<dde:mark type="component" name="example" host="this"/>--><div id="code-hk0h5" class="example"><pre><code class="language-javascript">document.body.append(

"Emty div is generated inside &lt;body&gt;:",
document.body.innerHTML.includes("&lt;div&gt;&lt;/div&gt;")
);
document.body.append(
Object.assign(
document.createElement("p"),
{ textContent: "Element’s text content.", style: "color: coral;" }
)
);
</code></pre></div><script>Flems(document.getElementById("code-hk0h5"), JSON.parse("{\"files\":[{\"name\":\".js\",\"content\":\"document.body.append(\\n\\tdocument.createElement(\\\"div\\\")\\n);\\nconsole.log(\\n\\t\\\"Emty div is generated inside <body>:\\\",\\n\\tdocument.body.innerHTML.includes(\\\"<div></div>\\\")\\n);\\n\\ndocument.body.append(\\n\\tObject.assign(\\n\\t\\tdocument.createElement(\\\"p\\\"),\\n\\t\\t{ textContent: \\\"Element’s text content.\\\", style: \\\"color: coral;\\\" }\\n\\t)\\n);\\n\"}],\"toolbar\":false}"));</script><p>To make this easier, you can use the <code>el</code> function. Internally in basic examples, it is wrapper around <code>assign(document.createElement(…), { … })</code>.</p><!--<dde:mark type="component" name="example" host="this"/>--><div id="code-smzmf" class="example"><pre><code class="language-javascript">import { el, assign } from "https://cdn.jsdelivr.net/gh/jaandrle/deka-dom-el/dist/esm-with-signals.js";
const color= "lightcoral";
document.body.append(
el("p", { textContent: "Hello (first time)", style: { color } })
);

document.createElement("p"),

You can declaratively sets any IDL and attribute of the given element. Function prefers IDL and fallback to the <code>element.setAttribute</code> if there is no writable property in the element prototype.</p><p>You can study all JavaScript elements interfaces to the corresponding HTML elements. All HTML elements inherits from <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement">HTMLElement</a>. To see all available IDLs for example for paragraphs, see <a href="https://developer.mozilla.org/en-US/docs/Web/API/HTMLParagraphElement">HTMLParagraphElement</a>. Moreover, the <code>assign</code> provides a&nbsp;way to sets declaratively some convenient properties:</p><ul><li>It is possible to sets <code>data-*</code>/<code>aria-*</code> attributes using object notation.</li><li>In opposite, it is also possible to sets <code>data-*</code>/<code>aria-*</code> attribute using camelCase notation.</li><li>You can use string or object as a&nbsp;value for <code>style</code> property.</li><li><code>className</code> (IDL – preffered)/<code>class</code> are ways to add CSS class to the element. You can use string (similarly to <code>class="…"</code> syntax in HTML) or array of strings. This is handy to concat conditional classes.</li><li>Use <code>classList</code> to toggle specific classes. This will be handy later when the reactivity via signals is beeing introduced.</li><li>The <code>assign</code> also accepts the <code>undefined</code> as a&nbsp;value for any property to remove it from the element declaratively. Also for some IDL the corresponding attribute is removed as it can be confusing. <em>For example, natievly the element’s <code>id</code> is removed by setting the IDL to an empty string.</em></li></ul><p>For processing, the <code>assign</code> internally uses <code>assignAttribute</code> and <code>classListDeclarative</code>.</p><!--<dde:mark type="component" name="example" host="this"/>--><div id="code-r0ona" class="example"><pre><code class="language-javascript">import { assignAttribute, classListDeclarative } from "https://cdn.jsdelivr.net/gh/jaandrle/deka-dom-el/dist/esm-with-signals.js";

You can use string (similarly to <code>class="…"</code> syntax in HTML) or array of strings. This is handy to concat conditional classes.</li><li>Use <code>classList</code> to toggle specific classes. This will be handy later when the reactivity via signals is beeing introduced.</li><li>The <code>assign</code> also accepts the <code>undefined</code> as a&nbsp;value for any property to remove it from the element declaratively. Also for some IDL the corresponding attribute is removed as it can be confusing. <em>For example, natievly the element’s <code>id</code> is removed by setting the IDL to an empty string.</em></li></ul><p>For processing, the <code>assign</code> internally uses <code>assignAttribute</code> and <code>classListDeclarative</code>.</p><!--<dde:mark type="component" name="example" host="this"/>--><div id="code-vc3nn" class="example"><pre><code class="language-javascript">import { assignAttribute, classListDeclarative } from "https://cdn.jsdelivr.net/gh/jaandrle/deka-dom-el/dist/esm-with-signals.js";
