javascript - Default function parameter value in safari is not working

I am using angularjs, and having problem with null assignment in safari only. Its working in chrome and firefox.

$scope.submit = function(id=null){
}

I am getting this error

SyntaxError: Expected token ')'

when I remove null, It just works. I don't know why !

$scope.submit = function(id){
}

Please help me to understand why this happening only with safari ?

4 Default function parameter values are an ES2015 feature that Safari apparently does not support. – Pointy Commented Apr 25, 2016 at 13:09

Default parameters from ES2015 are not yet supported in Safari. Please check the compatibility table.

At the moment the basic support provide Chrome 49 and Firefox 15.

But you can use the following ES5 code to achieve the same:

$scope.submit = function(id) {
  if (id === undefined) {
    id = null;
  }
}
