javascript - Use value from one object as key in another

Question

This is a homework assignment.

I'm trying to use the value from one object as a key for another.

for example...

    const myObj = {
    
    key: "myKey"
    
    }
    
    const myObj2 = {
    
     <--- here i need the value from myObj's key field. So, I thought to put something like myObj.key.value but that 
didnt work so I'm at a loss. I'm fairly new to javascript so this is a little over my head.
    
    }

Try this:

const myObj = { key: "myKey" };

const myObj2 = { [myObj.key]: "123" };

console.log(myObj2);
