oh noes

oh noes is confusing. he points out if i do a mistake , but not clearly. for example if  i  do this

var example = function(){

bacground(255,54,59);

};

instead of saying bacground is not definded he says you are missing a semicolon and i get confused and add one and he says you have ane unnessacary semicolon. i need to correct my mistakes on my own and get confused then.

please make ohnoes more better
