Vue.js 2 Cookbook

How it works...

In this recipe, we used an option called watch, which uses the following syntax:

watch: {  'name of sate variable' (newValue, oldValue) {    ...   } }

This is the counterpart of computed properties when we are not interested in a result after some reactive variable changes. As a matter of fact, we used it to just fire another method. Had we been interested in the result of some calculations, we would have used a computed property.
