Create an array of characters from specified range

Question

I read some code where someone did this in Ruby:

puts (\'A\'..\'Z\').to_a.join(\',\')

output:

A,B,C,D,E,F,G,H,I,J,K,L,M,N,O         


        

Answer 1

var range = [];
for(var i = 65; i < 91; i++)
{
 range.push(String.fromCharCode(i));
}
range = range.join(',');

gives range a-z, but i like the function option of some too.
