[Closed] Iterate over Arrays with map(Solution)


This is the solution for this exercise:


var oldArray = [1,2,3,4,5];

// Only change code below this line.

var newArray = oldArray.map(function(val){
  return val + 3;


[Closed] Filter Arrays with filter(solution)

I cleaned up your code.
You need to use triple backticks to post code to the forum.
See this post for details.

I also added spoiler tags because this is a solution.



@annajuare, I am glad you got the solution working, but please do not create multiple threads on the same topic. Also, please remember to put a solution in a spoiler :slight_smile:

I am going to close this thread, and I also closed your other solution thread. I kept your original thread open in case you have any more questions, or please message me if you have a question about me closing it. Again, nothing wrong with posting solution, etc. But there is no need for three threads on the same topic. Happy coding!
