You've heard, most likely, about elephants of modern web front-end development like Angular or React... May be read some articles about it, but jQuery looks so familiar, why bother?
You are right, you shouldn't. Just try Vue.
I love simple things. Here is real example of working Vue application.
<script src="https://unpkg.com/vue"></script>
<div id="app">
{{ greeting }}
</div>
<script>
new Vue({
el: '#app',
data: {
greeting: 'Welcome to your Vue.js app!',
}
})
</script>
More to come, stay tuned
