I have 4 defined private arrays defined in the constructor of my class.

Later down in one of the methods, im trying to push() variables into these arrays, but nothing seems to happen. I tried using this.arrayname.push(), but that doesn’t seem to work either.

any ideas? do i need to manually push them by this.arrayname[arrayname.length+1] = “”;
