JSTS IE11 is not working

[சுடர் SUDAR]

I have tried to use 1.6.2 version in IE11. But my page is breaking.

Sample code what  i am using...

My helper.js file

const jsts = require('jsts');

// import * as jsts from 'jsts'; --tried this as well

 const googleMaps2JTS = boundaries => {

   const coordinates = [];

   for (let i = 0; i < boundaries.getLength(); i += 1) {

     coordinates.push(

       new jsts.goem.Coordinate(

         boundaries.getAt(i).lat(),

         boundaries.getAt(i).lng(),

       ),

     );

   }

   coordinates.push(coordinates[0]);

   return coordinates;

 };

In react component i am trying import 

import {

  googleMaps2JTS ,

} from './_helper';

when i am using the above './_helper' import the react page is breaking...Please help me
