It can be done by putting the backslash \ in front of the character. It can be also implemented for other character.

We can also substitute the double quotation with ", and single quotation with ' — without using the backslash.

Let's use the earlier example: //this one element.innerHTML = "I am the \"injection\" result. Olé!"; //becomes this element.innerHTML = "I am the &quot;injection&quot; result. Olé!";
That also applicable for inserting actual HTML element with class or id or other attribute.
