I am looking for a reference of the array that we assign

sup.

array = [1,2,3,4]

array1 = array 
array2 = array

now, array1 and array2 hold ref. of the array so my question is how to know that this 2 array holds which object reference? in a value ? in a pointer? memory location?

You can simply use equality operator`===` – Code Maniac Apr 26 '19 at 12:30

Javascript doesn't expose pointers, memory locations or references. All you can do is pass objects around and test whether two variables hold the same object; – deceze Apr 26 '19 at 12:30
@CodeManiac I want the value of ref. a value that i can see === is not a value – Jigar Apr 26 '19 at 12:30
@deceze memory locations are not possible? – Jigar Apr 26 '19 at 12:31

Nope. That is entirely abstracted away. – deceze Apr 26 '19 at 12:31
@Jigar value will always be same in all refs, for example `data` will always be same or equal to `array1` and `array2` – Code Maniac Apr 26 '19 at 12:32
check this link may its helpful to you https://www.dyn-web.com/javascript/arrays/value-vs-reference.php – Syed Kashif Apr 26 '19 at 12:32
And yes, you can get stuff done in a language which doesn't expose details about memory, you just need to relinquish your C thinking. – deceze Apr 26 '19 at 12:33
