JS double-codegolf
Apr 23, 2014 - 23:39:22 (10y 216d) Google/translate1Thank You!0Good Post!0Bad Post! link

Today i set two challenges in one thread.

1: a script to return a given amount of fibonacci numbers but the adding of the script may only use two variables not the usual three, the third may only keep track of your sequence thus far for the purpose of a return.

2: a script to add 1+22+333+4444+55555+666666+7777777+88888888+999999999, without just cheating and using the numbers themselves.

good luck and have fun.. Smile

Seriously ?
What makes you think we couldn't have removed the "function" and replace return with alert ? We thought, or at least I did, that we're going with some implicit "standard". Smile

*EDIT*
#1 79 chars

GeSHi`ed javascript code

1	x=prompt();for (c=[],f=[1,0],i=0;i<x;i++){c.push(f.reverse()[0]+=f[1])}alert(c)
