How to check if two vars have the same reference?

Question

How can you check if two or more objects/vars have the same reference?

Answer 1

For reference type like objects, == or === operators check its reference only.

e.g

let a= { text:'my text', val:'my val'}
let b= { text:'my text', val:'my val'}

here a==b will be false as reference of both variables are different though their content are same.

but if I change it to

a=b

and if i check now a==b then it will be true , since reference of both variable are same now.
