@pcorpet this is certainly acceptable, but the readonly modifier only affects the implementation. Since this is just a declaration without an implementation, I'm curious. Why do you think this might be a useful addition?

[pcorpet]

readonly React.ReactNode[] actually makes the array readonly not the react node. This is an indication that the Trans component has no intention of modifying the array (appending, sorting). This is useful as I have a readonly array myself that I want to set as components prop.

const homeLinkComponents = [<a href="/" />] as const

<Trans components={homeLinkComponents} i18nKey="Go <0>home</0>" />

That currently fails with:

error TS4104: The type 'readonly [Element]' is 'readonly' and cannot be assigned to the mutable type 'ReactNode[]'.

Ok, makes sense. I would like you to add a usage test to the test/typescript dir and push it here so that we have no regressions.

Thank you!

@jamuhl this can be a patch release.
