Among these frameworks, React is the most popular and used framework as it is used to develop and operate the dynamic User Interface of the web pages with high incoming traffic. It makes the use of a virtual DOM and hence, the integration of the same with any application is easier. React is backed by Facebook and was open sourced by in 2013. Since then it got its popularity and has a very huge developer fan base and communities who constantly do their contributions.
Vue is also there in the market, but it is young and it gained it's popularity as its easy to learn and can be used for creating various types of web-applications. Though finding a job with Vue skills may take a while, as most of the companies prefer React or ANgular over Vue JS.
Angular is developed and maintained by Google and Google uses it in several internal products as well as the Google Adwords application. That's why Angular is trusted in the developer community. But being there in the market for quite a long time it is used by many companies and enterprises.
Now in terms of getting a job, as per the records from different job portals, there are tons of React and Angular jobs in the market when compared to Vue jobs. Lots of companies have adopted these technologies, hence creating many jobs in the market. If you search for jobs on a job portal, you will see that there's a very high demand for React and Angular JS developers. So in my opinions, you should go with React JS if you want to get a good job.
