Can someone explain how does the map object work? I have been having trouble understanding it, despite seeing it in multiple occasions in the curriculum up until now. And specifically, how does it affect this leaderboard we are trying to build?

Hello! Try reading this:
and this:
The challenge is using the map array method and not the Map() object.
Not sure I understand the question. What specifically are you asking about?
Hi @raven1177
Array.prototype.map(), or more simply map() is a simple array function, which is a method on the array object prototype.
So basically, the .map() method is used on an array, a call back function does something to each element in the array, without modifying the original array.
For this practice project, it is getting data from the freeCodeCamp website:
Then, instead of using lines and lines of code, using the .map()method you eventually produce something like this:
Happy coding
