using variable name in lodash collection

Question is bit crazy. Is there any possibility to using variable name instead of another, clearly, consider the following code where I have to switch over to any variable name "people" or "student" accordingly

 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);
