panic-fn


Functional way of throwing errors in JS/TS

Why?

Have you ever tried to do this?

``ts
callback(() => throw new Error("Not implemented"));
// or this
doStuff(value ?? throw new Error("No value provided"));
`

But got Uncaught SyntaxError: Unexpected token 'throw'.

With panic-fn it works as expected.

`ts
callback(() => panic("Not implemented"));
// or this
doStuff(value ?? panic("No value provided"));
`

You can also throw custom errors:

`ts
panic(new SyntaxError(Unexpected token 'throw'));
`

Installation
