The idea behind this is to speed up cluster resources such as garbage collection, reduce image transfer over the network, and accelerate the application launch. In case the pod has more than one container, we’ll need to specify as the last argument the container name, in this case, pxc, which is the container running the mysqld process.

When the JavaScript engine runs a garbage-collection process, the man object will be removed from memory and from the WeakMap that we assigned it to. As in every programming language, memory management is a key factor to consider when writing JavaScript. This is because it is a weak reference, and it doesn’t prevent garbage collection.
