Question

The _______________ file defines some metadata for your project and, most importantly, declares React-Native as a dependency of your project.

1. None of the options

2. index.android.js

3. package.json

4. index.ios.js

Answer 1

Correct ans is package.json
The package.json file is no surprise for those who already worked with Node.js; it defines some metadata for our project and, most importantly, declares react-native (this time, the real thing, i.e., the actual framework that makes our application possible) as a dependency of our own project.
