Data-driven views in Vue

Data-driven views in Vue are achieved with the help of reactivity.

What is reactivity?

To grasp the concept better, let's look at an example code in which there is no reactivity. We will use an example that is very similar to the one we had in the previous chapter, when we were comparing Vue and vanilla JS. In the original example, using JavaScript, we created an unordered list and three list items inside of it. The values of the three list items were added from an array we declared, and the unordered list was populated with these list items using a for loop.

This time, we will do something slightly different. To see the example as a pen, visit https://codepen.io/AjdinImsirovic/pen/JZOZdR...
