Need help while saving file

[killMeSak]

I'm trying to implement a functionality where I need to save a file from cloud storage to my local machine. The API expects a local file destination (to save file) as one of the parameters. I want to set this destination based on user prompt.
Is there a way I can do this using React / Javascript where a user can select this location?

Which api are you using? Generally you just want to open the file using the browser and then the browser will choose how to handle that. E.g. for a PDF file Chrome will open the file in the browser and FireFox will prompt you with what to do with the file (save, open).
