	Array mutations returning a new array

	Adding item to an array (list, item)
	return [...list, item];

	Remove item from index (list, index)
	return list
	.slice(0,index).concat(list.slice(index+1));

	return [...list.slice(0, index),

	Remotes
	Show tracked / untracked info for local branches
	$git remote -vv

	Clean up traked info for remote branches
	$git remote prune <remote>

	To update your local branch with remote

	Engagement
	User engagement levels can vary depending on the app or service.
	It could vary from daily to monthly visits, but it also relates to the depth and breadth of usage across the various touch points.

	DAU/MAU
	Daily active users/ Monthly active users. This metric is used to measure the depth of engagement of a company's users.
	Example: While the monthly user count was enormous, the DAU over MAU revealed that most of those users only log in sporadically.

	Mobile Retention Rates
	~80% of users are lost in the first month.

	## Managing tags

	# delete local tag '12345'
	git tag -d 12345
	# delete remote tag '12345' (eg, GitHub version too)
	git push origin :refs/tags/12345
	# alternative approach
	git push --delete origin tagName
	git tag -d tagName
