Angular 6.1.0+ Answer

Use the built-in keyvalue-pipe like this:

    Key: {{item.key}} and Value: {{item.value}}

or like this:

    Key: {{item.key}} and Value: {{item.value}}

where mySortingFunction is in your .ts file, for example:

mySortingFunction = (a, b) => {
  return a.key > b.key ? -1 : 1;
}

You won't need to register this in any module, since Angular pipes work out of the box in any template.

It also works for Javascript-Maps.
