Blog ≫ 2013 ≫ Can you javascript under pressure?

This tested our brains ¹ at work today. Here is my solution to the last one:

function arraySum( i ) {
  return i.reduce( function ( a, b ) {
    if ( b instanceof Array ) b = arraySum( b );
    if ( typeof b !== 'number' ) return a;
    return a + b;
  }, 0 );
}

I was dead slow as I kept insisting on using reduce, and forgetting what the params are for it, but I got there in 16 mins.

(and I took a phone call in the middle of that)
