*/** IE9, IE10 and IE11 requires all of the following polyfills. **/* *import 'core-js/es6/symbol';* *import 'core-js/es6/object';* *import 'core-js/es6/function';* *import 'core-js/es6/parse-int';* *import 'core-js/es6/parse-float';* *import 'core-js/es6/number';* *import 'core-js/es6/math';* *import 'core-js/es6/string';* *import 'core-js/es6/date';* *import 'core-js/es6/array';* *import 'core-js/es6/regexp';* *import 'core-js/es6/map';* *import 'core-js/es6/set';* Am Mittwoch, 23.
