JavaScript `this` keyword

Each time the function is called, this refers to the HTML element that is currently handling the event.

In JavaScript this always refers to the “owner” of the function we are executing, or rather, to the object that a function is a method of. When we define our  function doSomething() in a page, its owner is the page, or rather, the window object (or global object) of JavaScript. An onclick property, though, is owned by the HTML element it belongs to.
