Completely lost with this objects. Why do i get undefined - maybe the issue is hidden under the eval method.

Answer 1

You get undefined because data property does not exists in goblin object

You can do this and it will work:

document.write(eval("`${data}-of-${gobMobs[goblinInd].name}-${gobMobs[goblinInd]."+data+"}<hr />`"));

Answer 2

document.write(`${data}-of-${gobMobs[goblinInd].name}-${eval("gobMobs[goblinInd]." + data)}<hr />`);

You were kind of right in that the issue was with eval(). The issue was that the code was checking for gobMobs[goblinInd].'name' rather than gobMobs[goblinInd].name and so on.

Answer 3

Thank you for your answers
