insertAdjacentHTML() is an useful JavaScript function that can be used to insert HTML content at a specified position into DOM tree.
This function does not reparse the element it is being used on, and thus it does not corrupt the existing elements inside the element. This make it much faster than direct innerHTML manipulation.

Syntax:
element.insertAdjacentHTML(position, content);
- position - is the position relative to the element, and must be one of the following strings: - content - is a string with the HTML content that will be inserted in page.
