-Throws an exception that displays the values for `actual` and `expected`

 ## assert(value[, message]), assert.ok(value[, message])
 
 Tests if value is truthy. It is equivalent to
 `assert.equal(!!value, true, message)`.
 
-## assert.equal(actual, expected[, message])

-Tests shallow, coercive equality with the equal comparison operator ( `==` ).

-( `!=` ).
