Creates an new object of type val. The parent argument is optional; If it
is supplied, the object will be parented to that object.

**Performance note:** When the `Class.Instance.Parent|Parent` of an object is
set, Luau listens to a variety of different property changes
for replication, rendering and physics. Therefore, it is recommended to
**set the Parent property last** when creating new objects. As such, you
should avoid using the second argument (`parent`) of this function. You
can read [this thread on the developer
forum](https://devforum.roblox.com/t/psa-dont-use-instance-new-with-parent-argument/30296)

This function returns immediately if possible, but can yield the thread that called it until it can return a value.

This member doesn’t appear in the object browser and is not intended for widespread use.

This member is only accessible only through the command bar. Attempting to access this member from scripts causes an error.

This function can’t pause the Lua thread that called it.

Attempting to access this member in scripts causes an error. You might be able to access this member from Roblox Studio's property window.

This member doesn’t appear in Roblox Studio’s Object Browser.

You can’t create an instance of this class with the Instance.new constructor.
