reactjs - Should I update lists in place with React? -

-

to delete item list, created new list not contain deleted item, , replaced old list new. "right" way or should edit list in place? suspect may inefficient js.

destroy: function(chosenitem) {   var newitems = this.state.items.filter(function(item) {     return chosenitem.id != item.id;   });   this.setstate({items:newitems}); }

a couple of things:

  1. if such items have sort of persistence mechanism attached, consider using action architecture [see flux, reflux...], not set state of component directly, delegate deletion separate entity, later on notify component of update;

  2. creators of react evangelise immutable objects in order work w/ react, choice fine.

i realize question might seem trivial some, it's these types of things find myself fighting quite bit , want make sense of despite seeming losing battle in .net (for me anyway). so, if following: using system.web; ... applicationuser user = system.web.httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); that produces error in title , red getowincontext() , error cannot resolve symbol 'getowincontext()' however, if following (remove system.web in front of httpcontext ), works expected (or @ least no errors): using system.web; ... applicationuser user = httpcontext.getowincontext().getusermanager<applicationusermanager>().findbyid(system.web.httpcontext.user.identity.getuserid()); however, if (same line that's working using system.web commented out): //using system.web; ... applicationuser user = httpcontext.getowincontext().getusermana...

there new feature in mercurial 3, called 'graft' (graft local). job of moving change-set different branch. is there way "copy" change-set branch? i interested in in moving stuff qa branch production branch, still need code reside in qa. want copy. found , have tried few things, maybe it'll become clear more tinkering , reading... does have better way of 'cherry picking' change-sets move cross branch (or trunk)??? graft copies changesets, doesn't move them. hg graft (emphasis mine): this command uses mercurial's merge logic copy individual changes other branches without merging branches in history graph. known 'backporting' or 'cherry-picking' . default, graft copy user, date, , description source changesets.
