How to read out property minimum-stability?
Following code fails by throwing out error:qnips_JSON_Loesung.html:112 Uncaught ReferenceError: stability is not defined
output+="<th class='spalte'>"+daten.minimum-stabilty+"</th></tr>";
By the way, following construct works quite fine:
output+="<th class='spalte'>"+daten.keywords+"</th></tr>";

Answer 1

The - makes JavaScript think it's a calculation.
Either remove that when the file is created or access it like a map.

Answer 2

Here daten.minimum-stabilty is being confused with this expression (i.e. daten.minimum - stabilty). It thinks to subtract between daten.minimum and stability
To access a key that contains dash or other characters that are not permissible to be appear as an identifier, use brackets notation like this
daten["minimum-stabilty"];
Have you tried like this to access the json key that contains - ?
var json_with_dash_key = daten["minimum-stabilty"];
output+="<th class='spalte'>"+ json_with_dash_key +"</th></tr>";

Answer 3

Using daten["minimum-stabilty"] should work fine
Other alternatives are also suggested in the older post related to this problem: Unable to access JSON property with "-" dash

Answer 4

Following code solved my problem:
for(let j in daten["require-dev"]){
output+="<label> Version "+daten["require-dev"][j]+"<br></label>";
}
