I have javascript classes in multiple files. I would like to call a function from a given class by only supplying their names as arguments.

class Index{
    constructor(){
        this.Loader("test", "TestFunc");
    }

    Loader(cname, fname){
        const template = require(`./${cname}.js`);
        const object = new template();
        object[fname].apply();
    }
}

new Index();

module.exports = class Test{
    constructor(){
        this.text = "this text should appear";
    }

    TestFunc(){
        console.log(this.text);
    }
}

When the instance of the Test class gets initialized the constructor will run and prepare the value, but when I call TestFunc via the apply function the same values appear undefined and the error "Cannot read property text of undefined" gets thrown. When calling the function normally via object.TestFunc(); no such error is present.
