how to make a app communication and websites .how many languages should I have to learn ?

Answer 1

Hi Harry Singh 👋! You could build a single backend API and interact with it from your mobile app and website. This API could be a GraphQL API (recommended) or a RESTful API.
Both the website and the mobile app would make calls to the same API, and the API would make calls to the database to fetch the data that's needed by both interfaces.

The languages can vary but since you'd be working with JSON, these would be the key ones: JavaScript, NodeJS, MongoDB and frameworks/libraries like React, Express, Angular would be great too.

Here's a cool article about GraphQL if you're interested in reading more about it: https://medium.freecodecamp.org/so-whats-this-graphql-thing-i-keep-hearing-about-baf4d36c20cf
