   var a = 1; 如何让 a == a.value;

   var a = 1;
   
   //code
   
   console.log(a == a.value); // true

   解法：

   因为 a属于Number类型，所以我们可以考虑从Number.prototype` 入手

   var a = 1;
   Object.defineProperty(Number.prototype,"value",{
       get(){
           return this;
       }
   })
   
   console.log(a == a.value)
