Getting Started 7 Two-way data binding Two-way data binding means that if you change the value of a model in your view, everything will be kept up to date. 2.3 Comparison with jQuery. Probably all of you have a basic experience with jQuery. If you don’t, it’s okay, the use of jQuery in this book is minimal. When we use it, its only to demonstrate how things can be done with Vue instead of jQuery and we will make sure everybody gets it. Anyway, in order to better understand how data-binding is helping us to build apps, take a moment and think how you could do the previous example using jQuery. You would probably create an input element and give it an id or a class so you could target it and modify it accordingly. After this, you would call a function that changes the desired element to match the input value, whenever the keyup event happens. It’s a real bother. More or less, your snippet of code would look like this. 1 2 3 Hello Vue 4 5 6 7 Greetings your Majesty! 8 9

Of course, jQuery is a powerful JavaScript library for Document Object Model (DOM) manipulation but everything comes with its ups and downs!
