but i have a error

Cannot read properties of undefined (reading ‘setFromAxisAngle’)

Yes your quaternion (this.rotateQuaternion) is not initialized. You need to call new Quaternion() somewhere otherwise it will be undefined
I recommend to do it in awake

this how we do rotateTowards in unity
by user 274576156684976128
and this is three.js
by user 274576156684976128
this.model.quaternion.rotateTowards
by user 274576156684976128
I need make new vector and then assign it to the rotation?
by user 274576156684976128
No, you use a quaternion in threejs. three.js docs
But the code sample you sent does not initialize your variable here: rotateQurternion : Quaternion this is how I define it
Instead you need something like this:
rotateQuaternion : Quaternion = new THREE.Quaternion()
then you can use it with this.gameObject.quaternion.rotateTowards(this.rotateQuarternion, 0.2)
Otherwise this is the error you get 
Assignment to constant variable.

give me this error
by user 274576156684976128
rotateQuarternion= new Quaternion();
by user 274576156684976128
There is a important difference between Vector3 and Quaternion in threejs and Unity. In Unity you deal with value types and in threejs these are reference types so you need to initialize / new them before you’re able to use them
like this no error

I know

would be helpful if you could send a bigger chunk of your script - makes it easier to help
