How to use the @material/floating-label/component.MDCFloatingLabel function in @material/floating-label

      labelFactory: MDCFloatingLabelFactory = (el) => new MDCFloatingLabel(el),
      outlineFactory: MDCNotchedOutlineFactory = (el) => new MDCNotchedOutline(el),

      labelFactory: MDCFloatingLabelFactory = (el) => new MDCFloatingLabel(el),
      lineRippleFactory: MDCLineRippleFactory = (el) => new MDCLineRipple(el),

        if (labelFactory === void 0) { labelFactory = function (el) { return new MDCFloatingLabel(el); }; }
        if (lineRippleFactory === void 0) { lineRippleFactory = function (el) { return new MDCLineRipple(el); }; }

        if (labelFactory === void 0) { labelFactory = function (el) { return new MDCFloatingLabel(el); }; }
        if (outlineFactory === void 0) { outlineFactory = function (el) { return new MDCNotchedOutline(el); }; }
