How to load text from file into TextArea by line break?

Question

Qt

import QtQuick 2.9
import QtQuick.Controls 1.4
import QtQuick.Controls.Styles 1.4


TextArea {
    id: editor

    text: "G0 X11 Y0"
    font.pixelSize: 10
    textFormat: TextEdit.RichText
    selectByMouse: true

    function loadTextFile(fileUrl){
        var xhr = new XMLHttpRequest;
        xhr.open("GET", fileUrl);
        xhr.onreadystatechange = function () {
            if(xhr.readyState === XMLHttpRequest.DONE){
                var response = xhr.responseText;
                console.log(response)
                editor.text = response
            }
        }
        xhr.send();
    }


    Component.onCompleted: {
        loadTextFile("../../res/gcode/example1.gcode")
    }
}

File content:
G0 (Rapid to start) X1 Y1
G0 X1 Y1 (Rapid to start; but don't forget the coolant)
M2 ; End of\n program.

The file is loaded, but for some reason everything is in one line, line breaks do not smell. Although in console.log(response)
the text is output to the console with line breaks. Help a beginner
