Treble: How do I check if it is enabled on my device? Title says it all

By way of background Project Treble was announced with release of Oreo to speed up OS updates by reducing OEM delay . Devices running Oreo out of the box are expected to have it , so how do I check if my device has it and I can expect faster updates?
Works on unrooted devices also

Install Termux and run getprop ro.treble.enabled

It returns true if your device supports and false if it doesn’t

With adb

adb shell getprop ro.treble.enabled
