Having this knowledge, the module calculates how much memory object will allocate.
npm install object-sizeof
var sizeof = require'object-sizeof';// 2B per character, 6 chars total => 12Bconsole.logsizeofabc: 'def';// 8B for Number => 8Bconsole.logsizeof12345;var param ='a': 1'b': 2'c':'d': 4;// 4 one two-bytes char strings and 3 eighth-bytes numbers => 32Bconsole.logsizeofparam;
