Hi, No stupidity here - FlexJS is complex.
For the JavaScript side of FlexJS, createElement is the place where the HTML element gets made that corresponds to the component being made. Most of the time that is a <div> (see UIBase). Button uses it to make a <button>. Each FlexJS UI component has a .element property which is the main HTML element (e.g., a <div> or <input>). Each FlexJS UI component has a .positioner property which is the HTML element used to size and position the FlexJS component. Most of the time .element and .positioner are the same. In some cases, .element might be a <input> as it is the element of concern, but the .positioner might be a <div> in which the .element is placed. I believe this is true for complex components like Radio and ComboBox (not 100% certain - aging memory - but there is at least one component that uses them separately). This lets you add things to the .element (via the FlexJS addElement() function) and have the component¹s x, y, width, and height affect the .positioner so every HTML thing within the positioner is sized and moved together. element.flexjs_wrapper allows the FlexJS JavaScript code to backwardly reference the FlexJS class. Sometimes the JavaScript ³this² will be the HTML element itself, so we can quickly get to the FlexJS class instance using the .flexjs_wrapper. I can tell you it has come in handy sometimes. I hope this helps.
