code:

function makeQuery(queryObject) {    const query = Object.entries(queryObject)        .reduce((result, entry) => {            result.push(entry.join('='))            return result        }, []).join('&')    return `?${query}`}

sample:

const queryObject = {name: "nameValue", code: "codeValue"};const objectEntries = Object.entries(queryObject) => [["name","nameValue"],["code","codeValue"]]const arrayReduce = objectEntries.reduce((result, entry)=> {　　result.push(entry.join("="));　　return result}, []) => ["code=codeValue","name=nameValue"]`?arrayReduce.join('&')`
