ActivatedRoute.params forEach method vs subscribe method

Question

I know that both of ActivatedRoute.params.forEach and ActivatedRoute.params.subscribe will return the paramaters set into route config.

Into my configuration for example:

{ path: 'auditioning/:casterType/list', component: AuditionComponent }

When I check the parameters I do this:

this._activatedRoute.params.subscribe( (params) => { console.log(params) // return object of parameters } );

Or

this._activatedRoute.params.forEach( (params) => { console.log(params) // return object of parameters } );

When I should use forEach or subscribe when getting params into path because both of them return the result what I want?

What is the best practice?

When you see the Docs it is of type Observable,

So I always use the

this._activatedRoute.params.subscribe( (params) => { console.log(params) // return object of parameters } );

I hate using forEach on observables as it might cause a lot of troubles.
