Primitive types and reference types - 

let a=3;
let b=a;
a=4;

//callstack

a ---> 0001 ---> 3
b ----> 0001  
 a-----> 0002 --->4
obja ----> 0004 ---> 0003
objb ----> 0004 ---> 0003 

//Heap stack
 0003  ---> {
    name : 'mani'
 }

 const obja = {
    name:'cams'
}
const objb= obja;
objb={
    name:'hari'
}
obja.name='mani'
console.log(obja)
console.log(objb);
