I am looking to obtain the forward vector of an Object3D in Three.JS
var forward = new THREE.Vector3();
object.getWorldDirection(forward);
Is there a way to retrieve the right-hand side vector of the object within Three.JS framework?

If you're seeking help with three.js, my top advice would be to avoid searching for 'three.js' directly on Google.
I refrained from using 'three.js' in my searches and stumbled upon similar queries from individuals in a Unity community...
Through this approach, I discovered a rather simple (albeit slightly hacky) solution that effectively works in three.js.
You can start off with a basic right-hand vector
var right = new THREE.Vector3( 1, 0, 0 );
And then simply adjust it based on the object's .quaternion property...
right.applyQuaternion( object.quaternion );
This method allows you to determine any direction relative to the object's rotation, assuming it is normalized.
