I initialized i18n translation object once in a component (a first component that loads in the app ). That same object is required In all other components. I don't want to re-initialize it in every component. What's the way around? Making it available to window scope doesn't help as I need to use it in the render() method.
Please suggest a generic solution for these problems and not i18n specific solution.

You might not be aware that an import is global already. If you export an object (singleton) it is then globally accessible as an import statement and it can also be modified globally.
If you want to initialize something globally but ensure its only modified once, you can use this singleton approach that initially has modifiable properties but then you can use Object.freeze after its first use to ensure its immutable in your init scenario.
const myInitObject = {}
export default myInitObject
then in your init method referencing it:
import myInitObject from './myInitObject'
myInitObject.someProp = 'i am about to get cold'
Object.freeze(myInitObject)
The myInitObject will still be global as it can be referenced anywhere as an import but will remain frozen and throw if anyone attempts to modify it.
Example of react state using singleton
(see UserContext.tsx)
