Answer 1

UPDATE February 2020
If anyone still need help with this, mix already provide a babel compilation to es5:
A slight variation of mix.scripts() is mix.babel(). Its method
signature is identical to scripts; however, the concatenated file will
receive Babel compilation, which translates any ES2015 code to vanilla
JavaScript that all browsers will understand.
You can use it like this:
mix.babel(['public/js/es6file.js'], 'public/js/app.es5.js')

In order to compile your es6 code to es5 follow the following steps:
1) install the babel-env preset
npm install #babel/preset-env --save
And then declare it in your .babelrc in the root directory:
{
"presets": ["#babel/preset-env"]
}
2) compile your code using
npm run dev //for dev environment
or
npm run prod // for production environment

Answer 3

after a lot of search, I've found out that this Vuecomponent causes the error "https://github.com/godbasin/vue-select2" how can I compile it to es5.
the edge console error:
Expected identifier, string or number
and the corresponding line that it shows is this:
setOption(val = []) {
this.select2.empty();
this.select2.select2({
-----> ...this.settings,
data: val
});
this.setValue(this.value);
},
sorry for taking your time
