Interview Questions
Q. 1 Coding Test: Platform used for coding test: https://codeinterview.io/

Ryan Dahls github url is https://github.com/ry .

Github provides information about his public commits in JSON format at https://api.github.com/users/ry/events/public .

 In the JSON data there is an attribute called "type" which denotes what kind of commit it was.

 Let's say that we give following score to Ryan Dahl based on the "type" of the commit

IssuesEvent = 7
IssueCommentEvent = 6
PushEvent = 5
PullRequestReviewCommentEvent = 4
WatchEvent = 3
CreateEvent = 2
Any other event = 1

Write a nodejs program which when executed prints the score of https://github.com/ry . The answer printed on the terminal should be like this.

'Ryan Dahls github score is XXX'

Calculate the score based on the item results returned only from first page of that API call. Do not worry about pagination.
