Vue usa lodash para dividir arreglos bajo demanda

### 根据数组中的对象值拆分数组
  var stu = [
                {
    
     name: '张三', score: 60 },
                {
    
     name: '李四', score: 40 },
                {
    
     name: '王二', score: 80 },
                {
    
     name: '王二', score: 90 },
                {
    
     name: '', score: 90 },
                {
    
     name: '', score: 90 },
                {
    
     name: '', score: 90 }
            ]
var group = _.groupBy(stu, 'name')
### 根据数组中的对象值是否为空拆分数组
stu .forEach(e =>
    e.name== void 0
        ? this.nulllist.push(e)
        : this.fulltlist.push(e)
)
