What could be the shortest code for filtering the following array in Javascript without any library?
My code is:
filtered_obj = _.where(obj, { name: "Alpha" });
This uses a JS library called underscore
.
Test case:
objs = [{'id':1,'name':'Alpha'},{'id':2,'name':'Beta'},
{'id':3,'name':'Gamma'},{'id':4,'name':'Eta'},
{'id':5,'name':'Alpha'},{'id':6,'name':'Zeta'},
{'id':7,'name':'Beta'},{'id':8,'name':'Theta'},
{'id':9,'name':'Alpha'},{'id':10,'name':'Alpha'}];
filtered_obj =[{'id':1,'name':'Alpha'},{'id':5,'name':'Alpha'},
{'id':9,'name':'Alpha'},{'id':10,'name':'Alpha'}]

@closevoter: Questions asking tips about golfing code are on-topic.

I used underscore which is
filtered_obj = _.where(obj, { name: "Alpha" });
then I am looking for not using any library. – Gupteshwari – 2016-07-18T06:54:02.5072I'm voting to close this question as off-topic because I agree with @Katenkyo and think this is a homework question in disguise. – Blue – 2016-07-18T07:51:46.153
@muddyfish Go ahead. Appreciate the help anyways. – Gupteshwari – 2016-07-18T07:54:05.377
Not sure whether is homework or should be closed, but certainly I would expect a tip to be formulated in more generic style. – manatwork – 2016-07-18T09:43:16.853
