In JavaScript the Strings have a .length property that gives you exactly what you want.

DOM objects have a innerHTML property that gives their content (or innerText if you want to ignore HTML).

Combining this with a method that fetches the object from the DOM has what you want: 

var length = document.querySelector('h2.h2').innerHTML.length;
