What is Vue.js used for?

Question

Vue.js

Now I'm studying Vue.js and I just can't understand why it is needed? They say it's a replacement for Jquery. I used to make menus, sliders, tabs, calculators using jquery. Now all this is done in native Js, why Vue.js? They say Vue.js makes SPA. SPA on Laravel + VUE. Question and on one Laravel it is impossible to make SPA? Can you please tell me where and what is Vue used for?

I'm learning Vue.js and I just can't figure out why it's needed

If you can't figure it out, then you don't need it. Put it aside and study something else.
