javascript - Whitelist a set of properties from a multidimensional json array and delete the rest -


for examples sake i'll use github api response data input.

https://api.github.com/users/unsalted/repos

i have list of properties want keep, rest want discard because want keep output i'm generating considerably more compact.

how can achieve goal without doing this:

      (var = tagged.length - 1; >= 0; i--) {           delete tagged[i].private;           delete tagged[i].owner.gravatar_id;           delete tagged[i].owner.url;           delete tagged[i].owner.followers_url;           delete tagged[i].owners.following_url;           delete tagged[i].gravatar_id;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;           delete tagged[i].private;        };

i using lodash in project lodash solutions more welcome.

for times sake didn't fill out rest of values idea...

for given object, can use _.pick keep properties specify; , can map on collection. so, end with:

tagged = _.map(tagged, function (t) {     return _.pick(t, ['properties', 'to', 'keep']); });

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds
