I was pretty hesitant of the Composition API in Vue, but the more we've been practicing TDD at my job, the more excited I am to use the new Vue API. Vue Test Utils is painful to use when testing logic in many places because of the way the object syntax works. Just from a testing standpoint, it should be a lot easier to test v3 applications as we move towards a React Hooks-like API, where everything is a function.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
