diferrence between new vue & vue.createapp

Question

I'm studing Vue.js and I have learned that every Vue application starts by creating a new Vue instance with the Vue custructor new Vue({ })).

So far everything is clear, untill t I came across Vue.createApp({ }) which I don't understand if it does the same job as new Vue({ })) ? and if they can they be used interchangeably ? is one more recommended than the other ?

Answer 1

it is different syntax for different vue versions from version vue 2.7 naruto you can only use createApp and for older versions you can only use new Vue
