Error messages for future reference

✖ Error: Invalid Character (typing ng --version in the terminal)
Solution: Use bash (workaround)
✖ Error: Property 'name' has no initializer and is not definitely assigned in the constructor.
Solution: Add "strictPropertyInitialization": false in the compiler options of the tsconfig.json or a default value to the property.
✖ Error: Can't bind to 'ngModel' since it isn't a known property of 'input'.
Solution: Add FormsModule and ReactiveFormsModule to the imports array in app.module.ts.
✖ Error: Can't bind to 'ngForOf' since it isn't a known property of 'tr'.
Solution: Add BrowserModule to app.module.ts or check for typos, ex: *ngfor, instead of *ngFor.
