Replies for: I know it is an extension of the topic... How can I add an argument to the callback-function? I want to sort Objects according to their properties....

Use a compare closure function.

const data = [ {name: 'Bob', age: 22 }, { name: 'Jason', age:33 }];
const newData = data.sort( compare('name') )

function compare(prop) {
    return function (a,b) {
    console.log(prop) // outputs -> name
    return -1; // sort stuff
  }
}
