Question

Okay, this code gives me exactly what I want but it seems that it could be cleaner, so here is the code:

colour = ["red", "white", "orange", "black"]  
x=[]  
colour.each_with_index do |c, i|  
   x[i] = "<a href='http://#{c}.test.com'>#{c}</a>"  
end  
tags2 = x.join(", ")  
p "The code ==>#{tags2}<=== " 

Any takers?

Answer 1

tags2 = colour.map {|c| "<a href='http://#{c}.test.com'>#{c}</a>" }.join(", ")

map just calls a block for every element in the array, then returns the result array.
