I’m not sure about the questions, anyway as far as i can see :

return this.color=== itemyellow ? this.item="yellow" : etx
how do i put two possible outcomes like so
itemyellow or itemred?

This snippet works ( parenthesis added for sake of clarity)

let color, itemRed, itemYellow;
color = itemRed;
color === (itemYellow || itemRed) ? item = "yellow" : item = "red";
console.log(item);    // yellow

how do i make the selected item green? the active “item” that is

If i read it correctly you’re assigning the ‘.active’ class to the element “li” when “selectedItem == item”; that said, to make the element green just work on the ‘.active’ css class ^^

Hope it helps^^

Mh…i just copy pasted that code into codepen here and it works fine ^^
At the moment i can’t test it into angular ( i detonated windows this morning, still setting up my brand new Debian copy :D) but i can’t imagine why it shoudn’t ( here typescript operators )

Hope it helps^^
