    1. Cursed code snippets: #JavaScript custom elements edition. stackblitz.com/edit/typescript-2k5dgd?file=index.ts
      A screenshot of a TypeScript code snippet. This snippet declares a web component named `MyElement` with an optional property named `prop`. Then it creates a new `Document` with `document.implementation.createHTMLDocument()`. With that document, it creates a new `MyElement` and assigns the string 'test' to `prop`. Finally, the snippet appends this element to the main document and logs the value of `prop`. A typical user would expect this to log 'test', however a comment indicates that this line actually logs `undefined`.
