17,901 PointsNo, when running the uglify task, Uglify responded with completed but we drop these variable and functions because they are unused.
It dropped a function that was being called else where and had no reference too, on the pages in the folder, but will be added at a later time. So I wanted to know how I can get NPM to not removed unused functions or variables.
I did look closer and realized most of what it removed was good, because I missed the fact it wasn't needed. But there was one function I still wanted to keep.

Why are you keeping a function that doesn't ever get called? If it's not yet used by your application then uglifyjs is supposed to remove it to reduce filesize. If you want to keep that function around for developing it later into something that will be called/used, then keep it in development only.
Check out the API https://github.com/mishoo/UglifyJS. There's a chance that the --reserved-names flag might accomplish what you are asking.
You could also cheat and call the function you want to keep somewhere in the code such as:
function keepThisFunction() { return 'foo'; }
const throwaway = keepThisFunction();
But this seems hacky and to run counter to the point of using these build tasks.
