javascript - Difference of method calling between object and function -


here code , fiddle:

var test = {     value : "sss",      func1 : function(){         console.log(this.value);     }    };  var test2 = function(){     return {         value : "sss",         func1 : function(){             console.log(this.value);         }     }; }();  test.func1(); test2.func1();

hey lads, what's difference between these 2 ways of method calling. have make test2 inmmediate invoke function execution make sure works. mean carry coals newcastle? 1 better or situation should use them?

hey lads, what's difference between these 2 ways of method calling.

there's no significant difference between 2 resulting objects have them.

which 1 better or situation should use them?

the second scheme offers option of having private variables in closure methods use this:

var test2 = function(){     var cnt = 0;     return {         value : "sss",         func1 : function(){             console.log(this.value);         },         getcnt: function() {             return ++cnt;         }     }; }();  test2.getcnt();    // 1 test2.getcnt();    // 2

you use second scheme when needed these private variables. otherwise, first option bit simpler , involves 1 less function call.

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 ...
