Last Updated: 4 February 2023

Creates an element from a string (without appending it to the document). If the given string contains multiple elements, only the first one will be returned.

  • Use Document.createElement() to create a new element.
  • Use Element.innerHTML to set its inner HTML to the string supplied as the argument.
  • Use ParentNode.firstElementChild to return the element version of the string.
const createElement = str => { const el = document.createElement('div'); el.innerHTML = str; return el.firstElementChild; };
const el = createElement( `<div class="container"> <p>Hello!</p> </div>` ); console.log(el.className); // 'container'
