This means that the code composer no longer has to copy in dependent packages to the source tree. The vendor folder is searched for when the GOPATH looks for dependencies. This is good for a number of reasons:

• We can keep local copies of external dependencies on our projects. This can be helpful if we want to execute our programs on networks that have limited or no external network connectivity.
• This makes compilation of our Go programs faster. Storing all of these vendored dependencies locally means that we don't need to pull ...
