数组对象去重

// 根据属性去重

1. repeatArr = (items=[]) => {
   const cache = [];
   items.forEach(item => {
   if(cache.find(c =>
   c.issuerId === item.issuerId &&
   c.ecuAddress === item.ecuAddress &&
   c.filename === item.filename &&
   c.dataBlockNumber === item.dataBlockNumber &&
   c.exceptionMessage.exception === item.exceptionMessage.exception &&
   c.exceptionMessage.activity === item.exceptionMessage.activity &&
   c.exceptionMessage.action === item.exceptionMessage.action
   )){
   return false
   };
   cache.push(item);
   return false
   });
   return cache
   };

2. repeatGroup = data => {
   const obj = {};
   return data.reduce((item, next) => {
   if (!obj[next.name]) {
   obj[next.name] = true;
   item.push(next);
   }
   return item;
   }, []);
   };
