How I can change title without ion-title

I want to change title in SPA.
But I don’t want use ion-title. How I can change title??

title is this.

Same question here. I found a few threads, e.g. this, this, also talked about difficulties around using ion-title for the browser title. It’d be much more convenient to separate this (title setting) feature out and public and make ion-title rely on that.
