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:

suppose, have 100 products in db, did indexing , created documents. added 10 more products db. now, should update/add these 10 products existing indexed document? doing is, deleting existing documents , doing indexing. think not proper way. please guide me in this. note: in between not changing in schema.xml , solrconfig.xml just add new / modified documents solr , that's it. there's no need delete entire index 1 update. if document id 1 has field title change foo bar , add document same id field index, keeping unchanged fields old values (for example 'text':'old value' , 'date' : 'old date') , title field set new foo value. solr (or rather solr , lucene) take care of rest.

it seems firebase ios implementation doesn't support offline caching of client model. means in practice that: for firebase apps requiring authentication, need first authenticate , wait firebase finish login (check user identity, open socket, etc.) before can start moving data. require 1-8 seconds (usually 2-5) depending on network conditions, @ least here in finland. after authenticating, firebase first downloads initial set of data , initializes client cache. time perform depends on size of data add listeners for, it's quite fast. the problem here if you're using firebase implement, example messaging app, you'd want show user cached version of message threads , messages, before actual connection backend server established. i'd assume correct implementation need handle: the client-side model <-> firebase json mapping (i use mantle this) persisting client-side model disk (manual implementation using nskeyedarchiver, or core data or such?) syn
