How to type variables used in [bracket] notation?

[nkoehring]

Related to question #174 (comment) but I'm not sure how well you can see answers after the question is marked as answered, so here for clarity a new one:

When using bracket notation with the i18nObject, like for example LL.foo[bar](), what type needs bar to be?

@nkoehring you are probably looking for something like this:

import type { Translations } from '$i18n/i18n-types'
const key = 'something' as keyof Translations['foo']
LL.foo[key]()

[nkoehring]

That works, thanks!

Important to note: If namespaces are used, the type should be Translations, plural, instead of Translation, because the former includes all Namespaces, the latter explicitly forbids namespace keys and would end up as never :

import type { Translations } from '$i18n/i18n-types'
const key = 'something' as keyof Translations['foo']
LL.foo[key]()

right, thanks for the update. I'll edit my answer above
