Can Vue.js replace Angular in MEAN stack?
Not anytime soon, as Angular is more popular than Vue. Although Vue js is a good option to use for a front end single page application. The major problem with Vue replacing Angular is that Angular has been around longer and is quite popular. Some developers might switch to Vue for their projects but overall it does not seem likely. Also Angular is very easy to learn and get started with.
