//Rather than defining containerRow as multiple hard coded elements:
containerRow { 
	backgroundcolor: #ffffff,
	opacity 90%,
	dropshadow: 4px color: #000000,
	corner-radius: 10pt,
 }

//We define those one use elements as classes, very simple building blocks:
containerCornerRadiusPrimary: {
	borderRadius: 6
}
containerColorPrimary: {
	backgroundColor: 'rgba(255,255,255,.9)'
}
containerShadowPrimary: {
	shadowColor: ‘#000000’,
	shadowOffset: {
		height: 4,
		width: 0
	}
}

//Then we can define containerRow using those building blocks.
containerRow: {
	containerCornerRadiusPrimary,
	containerColorPrimary,
	containerShadowPrimary,
}
