i wrote following practice code compare differences between named , anonymous callback function, named callback function throws errors, wondering why , what's right way of using named callback function. looking friends = ["john", "mike", "resch", "tony"]; friends.foreach(function(value, index) { console.log('index of ' + index + ', value is: ' + value); }); function iterate(value, index) { console.log('index of ' + index + ', value is: ' + value); } friends.foreach(iterate(value, index)); the last line should be: friends.foreach(iterate); this pass function , iterate , .foreach() can call , provide arguments parameters, value , index . by including additional parenthesis after it, iterate being called , (attempt to) pass foreach() returned value ( undefined default). the errors because value , index don't exist outside of iterate() . for comparison, equivalent of: ...
