In any prod-bound or team-bound contexts where more than 1 person works or anything is supposed to scale in the future this should definitely not be used. So now the approach of using window wouldn't work anymore. The const analytics now takes precedence over any DOM ID definition. That happens in enterprise applications extremely often because the 3d-party tracking tool needs access to it. analytics libraries might expose const analytics = whatever in the window scope. While doing this, the servlet will convert the. Libraries are polluting the global context too - because they have to. Generate a HTTP Servlet based code that will accept user information over a form and generate the code for us. On top of that comes another problem: You are polluting the global context. So the teams are suddenly very dependent on each other, communication effort increases, etc. So not only now the ID is double-placed but also the window is ambigious. Now because they allowed themselves to do so they would be allowed to add id='submitButton'. Just paste any text (such as URL) to the input and it will generate QR CODE immediately. Now imagine one team has the idea of using window for their component that they are building. Here is simple and quick QR code generator: //QrCode. You guys must be remembered that I said, were going to generate QRCode with Custom Object. Generally in JS we try to modularize more to enable teams to scale and be free from dependencies from other teams. If being used in non-prod envs such as showing something or Sandboxes then it can be very helpful (this is where I actually do use it).īut for prod it should be avoided as a guideline. But it's recommended to be avoided at all costs in programming because it opens up an option to be breached.Īnd the similiar goes for window. Security through Obfuscation is definitely working in the right context. It goes the same principle as always e.g. In production, as stated, it shouldn't be recommended to be used. The problem is that this is viewed from a 'small context perspective'.
