use of const seems to be unnecessary error

[ORESoftware]

I have a Node.js project and wanted to experiment with using this compiler to see what would happen,
I ran the transpiler like so:

$ java -jar ~/Desktop/closure-compiler-v20161201.jar --js_output_file=out.js lib/

and I get all these errors

I bet this is a duplicate issue. What is the status on this? Can I avoid this error? Should I bother "compiling" a node.js command line app?

[ChadKillingsworth]

NodeJS support isn't really there. The compiler doesn't have a way to recognize that require is a module loader without bundling the files together. You can get some type checking support by using the --process_common_js_modules flag, but it's going to bundle all of the files together.

In addition, the compiler does not yet have a way to recognize that builtin Node modules are external and can't be bundled.

Once #2130 lands, this will start being a possibility, but it's also non-trivial work.
