Does Salesforce apex transpiled into java or not ?

Hello Mohit,

In one embodiment, the Apex interpreter serves as a level of isolation between customer code and the host virtual machine (VM). The Apex interpreter may enforce governor limits and brokers requests to the underlying platform on behalf of customer code. In one embodiment, the Apex interpreter is not a full-fledged Java virtual machine. The Apex interpeter may delegate to a Java virtual machine (JVM) for various services. Garbage collection is an example of this. In one embodiment, the Apex interpreter is also able to delegate to the VM on a per type basis.

Apex Code runs in Java, but it is not a full VM, and will delegate various tasks such as garbage collection to the underlying Java VM
