This is taken from my course, Vue with Test Driven Development at udemy. Here is the discount link https://bafoly.com/?course=tdd-vue Computed properties allow us to declaratively compute derived values. However, there are cases where we need to perform "side effects" in reaction to state changes - for example, mutating the DOM, or changing another piece of state based on the result of an async operation. With Options API, we can use the watch option to trigger a function whenever a reactive property changes Like, subscribe, comment any interaction with my channel, means a lot.
