IE 11 Script1002 Array.Filter(x => ...) (Arrow functions)

Question

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

Answer 1

ie 11 not support arrow functions

try

var selectedRoles = vm.roles.filter(function(x) { return x.id === role.id; }); 

Answer 2

IE not supported arrow function check browser compatibility here. If you want IE support then use the normal function instead.

var selectedRoles = vm.roles.filter(function(x) {   return x.id === role.id });
