You have to test your code, so why not make the process as easy and painless as possible?
over the environment within which our code runs. Multiple operating systems, multiple
versions of operating systems, multiple browsers, and multiple versions of browsers, not
to mention plug-ins, extensions, different languages, zoom levels, and who knows what
else, all conspire to hinder the performance of our applications. These permutations
slow down, break, crash, and eat our applications for lunch. It’s a jungle out there! Serverside
environment. However, Rhino and Node.js applications do not have the full
gamut of mature tools, the testing procedures, and the ecosystem that other languages
do. Further, the asynchronous nature of Node.js complicates testing. It is interesting that
a language so intertwined with asynchronous execution has essentially zero built-in
support for that mode of execution.
this complexity is to take full control of what we actually do control: the code. Code
exists across a continuum, from someone else’s to yours on one axis and from legacy to
nonlegacy on the other.
