With the introduction of native BigInts (also known as Big Nums or Arbirtrary-Precision Numbers), in JavaScript, it's now easy to convert from arbitrarily-large ints to hex (which isthe gateway drug to typed arrays). However, there are somecaveats, particulary with negative numbers. But ...

Complete the method so that passing in RGB decimal values will result in a hexadecimal representation being returned. The valid decimal values for RGB are 0 - 255. Any (r,g,b) argument values that fall out of that range should be rounded to the closest valid value. The following are exam...
