-Throws an exception that displays the values for `actual` and `expected`
-separated by the provided operator.

 ## assert(value[, message]), assert.ok(value[, message])
 
 Tests if value is truthy. It is equivalent to
 `assert.equal(true, !!value, message)`.
 
-## assert.equal(actual, expected[, message])
-
-Tests shallow, coercive equality with the equal comparison operator ( `==` ).

-Tests shallow, coercive inequality with the not equal comparison operator
-( `!=` ).
