ES6 数组处理：将 ID 值转换为字符串并去除最后一个逗号

const arr = [{id: 0, name: '0'}, {id: 1, name: '0'}, {id: 2, name: '0'}, {id: 0, name: '0'}, {id: 1, name: '0'}, {id: 3, name: '0'}];\nconst updatedArr = arr.map((item, index) => {return {id: index.toString(), name: item.name};});\nconst result = JSON.stringify(updatedArr).replace(/},/g, '}');\nconsole.log(result);
