First of all, you have to look at the needs of your company. If your company only needs you to do java back-end things, then whether you want to learn or not depends on your personal pursuits and interests. If you learn by yourself, I personally do not recommend angularJS. You can choose one of the three angular2, react and vue; if your company not only You only need to do back-end things but also front-end things. At this time, you still need to score points. java后端的事情，那么学与不学得看你个人的追求和兴趣，自己学习的话，我个人不推荐angularJS,你可以在angular2、react和vue三选一；如果你公司不仅仅需要你做后端的事情还要做前端的事情，这时候还得分情况，你们公司前端用的是什么技术，如果是angularJS，那么肯定是要学的，如果不是angularJS，假设是vue什么的，那你还是要学vueWhat technology does your company use on the front end? If it is angularJS, then you must learn it. If It's not angularJS, if it's vue or something, then you still have to learn vue

To summarize, we give priority to learning the technologies that the company needs. If you are learning by yourself, you can learn it if you have pursuits and interests, and strive to become a full stack. Of course, technology selection is also more important. If the company does not use angularJS，推荐angular2、react和vuechoose one of the three, of course the front-end It updates very quickly, and there are many and complicated things. Without some love, it is difficult to learn for a long time
