This situation differs from the one discussed in Remove dom element without knowing its parent?, because their element has a parentNode.
While I am familiar with removing an element through its parentNode, creating a new element poses a different challenge as it lacks a parentNode entirely.
Hence,
a) How can I remove this element?
b) Is removal necessary? Or does the element get automatically cleaned up when there are no references to it?
The scenario: I am working on building automated tests for my JavaScript code using Mocha on the browser. My goal is to verify if child elements are correctly inserted into a specified parent element. I dynamically create the parent element before each test, but I hesitate to add it to the document. Yet, I want to ensure that I don't end up with a long list of unreferenced nodes lingering around.
var element = document.createElement('div');
console.log(element); // The div
console.log(element.parentNode); // null
element.parentNode.removeChild(element); // "Cannot read property 'removeChild' of null"
