I get a error message in IE11 but not in chrome the error is:

Script1002 Syntax error

My code is as follows

var selectedRoles = vm.roles.filter(x => x.id === role.id);

The line and column number of the error suggest that it is the arrow function => that IE11 does not like. However it works fine in Chrome and Edge
