MDN: In arrow functions, this retains the value of the enclosing lexical context's this. In global code, it will be set to the global object:

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/this

I wrote this code:

const outerObj = {
      lemon:5,
      obj:{
        egg:5,
        apple: () => {console.log(this)}
      }
    }
    
    
    
    outerObj.obj.apple()

Why global object printed? my arrow function doesn't have her own this, so she looks for her outer scope, and it should be the "this" of obj, so I expect to see { egg: 5, apple: [Function: apple] }, what I missed?
