如何取出所有的 projectList,放到一个新的数组中,
自己写了循环,然后遍历 list, 只拿到最后的两条数据,请问这里应该怎么写

for(var j = 0;j < data.length;j++){

  this.list = data[j].projectList

}

this.list = data.map(item => item.projectList).flat()

this.list = data.flatMap(v=>v.projectList)

上面是一些 ES6 的写法。下面开始说你这个怎么整

看你的代码,你重新给list赋值了,数组赋值应该用什么?push
