In Pulumi, you may want to cast a
pulumi.Output<T>value to a string for simple console log purposes or for use within a part of your script where a raw string is needed. However,
pulumi.Output<T>values represent a value which will be available in the future, not at the time of execution of your script, hence it requires a special method to deal with this.
To handle this, we can use the
applymethod available on instances of
pulumi.Output<T>. This method allows you to provide a callback function, which will be invoked with the eventual outputted value.
Here's an example of how to do it:

pulumi.Output<T>can be any data type such as string, number, custom interface, etc. The
applymethod can also return a different type, which will change the type of the output. For example:
myOutputNumberis of type
