updateMultiData(contracts, sender, dataKeys, dataValues, currency)

Feature	Return raw operation to update multiple data. The length of dataKeys must same with length of dataValues and contracts. (max length is 100) Note: Handler of contract also can execute the function.
Parameters	string | string[] contract address, // If given a string, it is automatically converted to an array filled with the same values. string sender, string[] dataKeys, (element’s max length is 200, must not contain: space / : ? # [ ] @) string[] dataValues, (element’s max length is 20000) string currency ID
Return Value	object update-data operation with multi items

example1. update data for each contract

const sender = "0x4526f3D0EdC63D9EaeCD94D56551e0f061CFCa47fca";
const currencyID = "MCC";

const contract = "0x87aCb45fFbB1507Be67102875EAc4Eb024306465fca";
const contract2 ="0xa6283308BBedbfB8041A2Ea950A11D142A0F4FD9fca"
const contracts = [contract,contract,contract2,contract2];
const dataKeys = ["key1", "key2", "key3", "key4"];
const dataValues = ["value5", "value6", "value7", "value8"];
const op = mitum.storage.updateMultiData(contracts, sender, dataKeys, dataValues, currencyID);

console.log(op);

}

example2. update four data about one contract (0x87…)

const sender = "0x4526f3D0EdC63D9EaeCD94D56551e0f061CFCa47fca";
const currencyID = "MCC";

const contract = "0x87aCb45fFbB1507Be67102875EAc4Eb024306465fca";
const dataKeys = ["key1", "key2", "key3", "key4"];
const dataValues = ["value5", "value6", "value7", "value8"];
const op = mitum.storage.updateMultiData(contract, sender, dataKeys, dataValues, currencyID);

console.log(op);
