Discussion on: Introducing Nexus.js: A multi-threaded JavaScript run-time

[Abdullah Ali]

Hi! Concurrent access to variables does not corrupt them or cause a race condition. All variables behave atomically in Nexus.

So, in this particular example

When two different execution contexts that share a closure variable are entered in parallel, one will acquire a lock

means that a listener will lock on parent closure right at the start of the function till its end? Or it will lock only from the time of identifier resolution for count to finishing its value reading?

[Abdullah Ali]

It will only lock upon access to the variable and then it will release the lock as soon as it is done.

Thank you.

You’re welcome :)
