Nodejs-assert Use Example

Example of use of the Assert assertion library in Nodejs:

Some rules can be found here:

• Equal, NotEqual, deepequal, notdeepequal: compare using the ' = = ' comparison. that is: The method without strict, using the ' = = ' comparison.
• Strictequal, Notstrictequal, strictdeepequal, notstrictdeepequal: compare using the ' = = = ' comparison. that is: A method with strict, using the ' = = = ' comparison.
