var a = 5;

function lol() {
 var a = 10;
 console.log(this.a)

 function kek() {
  console.log(this.a)
 }
 kek()
}

lol()

outputs

5
5

— Can somebody explain me why?
First console log prints 5 that makes sense as call site for lol function is global scope but for kek function call site is lol() then why its logging 5 instead of 10?
