关于二维数组的条件筛选输出

忽略掉全都是一样的信息这个“bug”，嫌麻烦所以复制的，题目是：输出所有是大一的女生，请问这代码哪写错了，为啥一个都输出不了呢，请指正

 var infos[["小a","女",21,"大一"],["小b","女",21,"大一"],["小c","女",21,"大一"],["小d","女",21,"大一"],["小e","女",21,"大一"],["小f","女",21,"大一"],["小g","女",21,"大一"],["小h","女",21,"大一"],["小i","女",21,"大一"],["小j","女",21,"大一"]];

 for(var i=0;i<infos.length;i++){
     var jr=infos[i][3];
     var wx=infos[i][1];
     if(wx=="女" && jr=="大一"){
         document.write(infos[i]+"<br/>");
     }
 }

    定义数组的时候少了个 “＝”

     定义二维数组的时候，需要加等号

    var infos = [["小a","女",21,"大一"]...]
