-See [#448](https://github.com/mishoo/UglifyJS2/issues/448) for additional details.
+`const` in `uglify-js@2.x` has function scope and as such behaves much like
+`var` - unlike `const` in ES2015 (ES6) which has block scope. It is recommended
+to avoid using `const` for this reason as it will have undefined behavior when
+run on an ES2015 compatible browser.
