Syntax error in IE using ES6 arrow functions

I have this piece of JavaScript code

price = price.replace(/(.*)\./, x => x.replace(/\./g,'') + '.')

This works fine in Firefox and Chrome, however IE gives me an syntax error pointing at => in my code.

Is there a way to use ES6 arrow syntax in IE?

Internet explorer doesn't support arrow functions yet. You can check the browsers supporting arrow functions here.

The method to solve it would be to make a good old regular callback function : 

price = price.replace(/(.*)\./, function (x) {
    x.replace(/\./g,'') + '.';
}

This would work in every browser.

IE doesn't support ES6, so you'll have to stick with the original way of writing functions like these.

price = price.replace(/(.*)\./, function (x) {
  return x.replace(/\./g, '') + '.';
});
