在lodash集合中使用变量名

Question

这个问题有点奇怪。是否有可能使用变量名而不是另一个变量名，考虑以下代码，我必须根据需要切换到任何变量名“people”或“student”。

 var people=[
      {name:"akash",age:25},
      {name:"abi",age:22}
   ];

 var student =[
     {name:"Sanjai",age:25},
     {name:"Ravi",age:35},
      {name:"Bopara",age:36}
 ];
var variables=["people","student"];

 var result= _.find(variables[0], function(o) { return o.age < 35; });
   console.log(result);

当然，只需要将变量放入数组中而不是字符串中：

var variables=[people, student];

完整范例：

var people=[
     {name:"akash",age:25},
     {name:"abi",age:22}
 ];

var student =[
     {name:"Sanjai",age:25},
     {name:"Ravi",age:35},
     {name:"Bopara",age:36}
 ];

var variables=[people, student];

var result= _.find(variables[0], function(o) { return o.age < 35; });

console.log(result);
