I know the function array.max() will give the maximum across the whole array, and array.max(1) will give me the maximum across each of the rows as an array. However, I'd like to get the maximum in a certain row (for example, row 7, or row 29). I have a large array, so getting the...

I have having some trouble printing a "char" from an ASCII value stored in an array. The goal overall is to read a string of input from the user, store that in an array.

In stead I want to do: for (i=0;i<source.length;i++) { target.push(source[i]); } Is there a way in javascript to do this more elegant, without explicitly coding a repetition loop?...
