Component Props More Than Strings

Before looking at validating props one needs to make sure they understand that a component prop can be any valid JavaScript value.

In the example below I setup several default props containing several different JavaScript values.

See the Pen qYgpqX by Bunlong (@Bunlong) on CodePen.

Note how the propArray and propObject were overwritten with new values when the MyComponent instance is created.

The main take away here is that you are not limited to string values when passing prop values.
