In the process of crafting an element from a string, without attaching it to the document, one must employ several steps. First and foremost, Document.createElement() is utilized to forge a fresh element. Subsequently, Element.innerHTML is harnessed to imbue this newly created element with the content provided in the form of a string. The function then leverages Element.firstElementChild to obtain the element representation of this string.

To execute this sequence, a function named `createElement` has been crafted. Within this function, a ‘div’ element is created using Document.createElement(), and the inner HTML is set to the string passed as an argument. Finally, the function returns the firstElementChild of the created element.

```javascript
const el = createElement(
  `<div class="container">
    <p>Hello!</p>
  </div>`
);

console.log(el.className); // 'container'
```

This snippet will generate an element with a class name of ‘container’.

To wrap up

In conclusion, the process of creating an element from a string, without appending it to the document, involves a series of steps. By utilizing Document.createElement() to create a new element, Element.innerHTML to set its inner HTML from a supplied string, and Element.firstElementChild to obtain the element version of the string, one can efficiently achieve this task. The `createElement` function encapsulates these actions, allowing for the creation of elements from strings with ease.
