Very simple question, how much data (bytes) do strings take up? Do they take up 1 byte per character?
I tried searching it up, but ws schools doesn't say...
I want to know this to reduce bandwidth in my web app.
Also, for anyone that knows, does socket.io automatically json stringify when using
String is a character array. So, it will take up roughly
sizeof(char) * noOfCharacters ignoring other fields in String class for now. Character can be of 1 byte or 2 bytes depending upon the system, the type of chars being represented- unicode etc.
However, from your question, you are more interested in data being transported over the network. Note that data is always exchanged in bytes (
byte) and thus string will be converted into byte representation first and then ported over.
To limit the bandwidth usage, you can enable compression, choose interoperable serialisation technique(protobuf, smile, fastinfoset etc)
