> Angular is a not a JavaScript framework, but a TypeScript framework. TypeScript likes to pretend it is safe because it is strongly typed. This is somewhat true, but TypeScript suffers from the exact same problem Java does - it is not null safe. Worse, because TypeScript has no runtime component and emits no warnings for many unsafe casts, the language only offers the illusion of safety. For instance, this is perfectly valid TypeScript code that raises no warnings.

TypeScript has compiler flags to give compiler errors when null errors are possible. You can also turn off the implicit "any" type and use linters to stop explicit use of it.

It's a pretty good compromise given it has to work with what's out there already and it's certainly an order of magnitude safer than plain JavaScript.
