"Mutating the immutable" is my personal favourite - the second line of code fails with an exception despite having already succeeded:

• DOMPurify

  DOMPurify - a DOM-only, super-fast, uber-tolerant XSS sanitizer for HTML, MathML and SVG. DOMPurify works with a secure default, but offers a lot of configurability and hooks. Demo:

You shouldn't roll your own for this. From what I've had to do web-wise, here's a few tools.

First, for the APIs, you need documentation: https://swagger.io/

From which you can generate JSON schemas and use those to validate in the browser and on the backend. https://www.npmjs.com/package/jsonschema

As well you should be writing a few more schemas for your application state and leverage the regex validation of your input components...

Speaking of which, you also need to sanitize out some potentially nasty input. https://www.npmjs.com/package/dompurify

Obviously this isn't everything and not perfect, but a lot of this tedium can be automated away if you have a few good examples of the happy path and some basic tests in place to prevent quick and dirty changes from poking holes in these layers.

  TypeScript is a superset of JavaScript that compiles to clean JavaScript output.

So TypeScript intentionally suppresses this kind of complaint when matching up function types even though it issues them when calling functions directly. The reason for that has a justification, but in contexts like this, I think it is a WAT-worthy interaction.
