Unable to minify Javascript error

[crabdul]

When I run hugulp the following error is encountered.

Do I need to modify the gulp settings so that I can minify javascript in ES6 syntax?

`crabs-MBP:KARAI cr.ab2$ hugulp build
[23:53:13] gulp-imagemin: Minified 0 images
assets/scripts/radio.js: line 20, col 11, 'template literal syntax' is only available in ES6 (use 'esversion: 6').
assets/scripts/radio.js: line 22, col 28, 'template literal syntax' is only available in ES6 (use 'esversion: 6').

No worries, I figured it out.
I changed the javascript parser dependency to uglify-es
