let versus var Treeshaking Issue Caused By Terser

• Operating System: Ubuntu 16.04.5
• Node Version: v10.14.2
• NPM Version: 6.70
• webpack Version: 4.29
• terser-webpack-plugin Version: 1.10

I've been advised that a Tree-shaking issue I'm having in Webpack may be being caused by terser:
webpack/webpack#8692 (comment)

If you scroll up from that comment, you can see the entire issue.

I'm I submitting this at the correct place?

@Lonniebiz no, tree shaking it is part of webpack, we just wrapper around terser, you can look source code and find what we do nothing only call terser

@evilebottnawi : When I turn on terser's warnings option, I do see that terser is responsible for dropping unused functions and that's what tree-shaking is all about, right? And, btw, the comment I referenced above (where terser is suspected) was made by (I think) the creator of webpack.

I see what you're saying, this plugin has nothing to do with terser's actual code.
