Is there a way to unset a const in the mongo shell.
When trying the delete operator, I get the following output:
> const myconst = {"test":123}
> myconst
{ "test" : 123 }
> delete myconst
false

Well, `const` declares a **constant** which namely never changes. In order to unset a **variable** see https://stackoverflow.com/questions/1596782/how-to-unset-a-javascript-variable – Wernfried Domscheit Mar 04 '21 at 13:13

@WernfriedDomscheit i understand that concept but if my server is running and i have got lots of these consts in the memory now i want to deallocate them what can i do then. As one way i suppose would be stopping the server and restarting it. – Naman Kumar Mar 04 '21 at 13:15

I doubt that a bunch of constant could stress your server. Other use `const` onl for **contants** rather than for variables. Apart from that: disconnect or closing your shell should be sufficient. Stopping the server should not have any effect on local variables. – Wernfried Domscheit Mar 04 '21 at 13:53
