Yes it's true indexOf() is faster than a RegExp. But in this case you must consider that you are running the indexOf() on the innerHTML, which isn't a field but a property. This means when you "call" the innerHTML a function behind it serialize the DOM into a string an return it. For this reason the innerHTML.indexOf() is slower than the HTMLDocuemnt.evaluate and String.indexOf() is faster than a RegExp. <p>Yes it's true indexOf() is faster than a RegExp. <br />But in this case you must consider that you are running the indexOf() on the innerHTML, which isn't a field but a property.
