We must remember that undefined should always be in single quotes, or the comparison will fail. It uses progressive JavaScript, is built with and fully supports TypeScript (yet still enables developers to code in pure JavaScript) and combines elements of OOP (Object Oriented Programming), FP (Functional Programming), and FRP (Functional Reactive Programming). Sign in I think the original idea was to include an if-statement whenever Blob or something similar was used, and to implement different logic for Node than for browserside Javascript. Edit: I think my issue is slightly different and posted it on Stack Overflow: https://stackoverflow.com/questions/64458225/angular-universal-external-dependencies-issues-webpack-server-config-js-nodeex. It can happen due to misspelled keywords or a mispositioned script tag. If they are, code is being executed on the server side, and wont have access to those variables, of course. "jsdom": "9.3.0".

There might be some addons/Library inclusions that must be included before DOM creation. Solution 1: Check whether browser or server-side execution, Solution 2: If error occurs while running on browser, [Solved] Error: Cannot find module node:events, [Solved] TypeError: toISOString is not a function, [Solved] TypeError: replaceAll is not a function, [Solved] TypeError: toUTCString is not a function, [Solved] TypeError: startsWith is not a function, [Solved] Objects are not valid as a React child.
