There is a similar object with arrays

var section = { link: [], filename: [], name: [], author: [], material: [], scale: [], date: [], museum: [], city: [], notation: [], };

How can I iterate through its values ​​in a loop to display them (I want to fill the table). Do nested loop? Why is this cycle not working?

 for (property in section) { property['filename'].forEach(function(item) { alert(item); }); }

property['filename'] - wrong in your case, because property is already a key.

Try something like this:

 for (property in section) { section[property].forEach(function(item) { alert(item); }); }
