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

Feature	Return raw operation for creating 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 create-data operation with multi items.

example1. create data to each contract

const contract = "0xb2310381f7E51a69d0C4cCdbE7a6DCB3B7353192fca";
const contract2 = "0xa6283308BBedbfB8041A2Ea950A11D142A0F4FD9fca";
const sender = "0x4526f3D0EdC63D9EaeCD94D56551e0f061CFCa47fca";
const currencyId = "MCC";
const contracts = [contract, contract, contract2, contract2];
const dataKeys = ["key1", "key2", "key3", "key4"];
const dataValues = ["value1", "value2", "value3", "value4"];
const op = mitum.storage.createMultiData(contracts, sender, dataKeys, dataValues, currencyId);
console.log(op)

// output

}

example2. create four data to contract (0xb2…)

const contract = "0xb2310381f7E51a69d0C4cCdbE7a6DCB3B7353192fca";
const sender = "0x4526f3D0EdC63D9EaeCD94D56551e0f061CFCa47fca";
const currencyId = "MCC";
const dataKeys = ["key1", "key2", "key3", "key4"];
const dataValues = ["value1", "value2", "value3", "value4"];
const op = mitum.storage.createMultiData(contract, sender, dataKeys, dataValues, currencyId);
console.log(op)

// output
BaseOperation {
