Go to your application root directory and run npm install
Your questions are under directory ./interview-questions. You only need to try to solve the first two, q1 and q2. The third problem is really just about your past experience facing similar challenges.
Run npm run test, you shall see failed tests. Your goal is to finish the implementations in ./interview-questions/q1.js and ./interview-questions/q2.js, so all tests can pass. You can NOT modify any existing files or logic except for q1.js and q2.js.
Good luck!
