Webpack's removes classnames when minifying/uglifying ES6 code with inheritance

[ericmorand]

This is a follow-up to #269.

This is still not fixed. Using this perfectly valid ES6 syntax:

class Foo {
    getConstructorName() {
        return this.constructor.name;
    }
}

let foo = new Foo();

console.warn(foo.getConstructorName()); // output "Foo" when non-minified; "" when minified

webpack will output "" instead of "Foo".

I insist on the fact that this is a perfectly valid syntax that totally respects ES6 specifications. There is not point arguing about that.

Because uglify-js doesn't support es6 syntax, please use terser plugin
