How to trim a string in Vue.js?

Question

Vue.js

Let's say I want only one letter to be displayed in {{message}} - the first one for example (not "Hello Vue!" but just "H"). How to do it in a simple way:

<div id="app">
  {{ message }}
</div>

var app = new Vue({
  el: '#app',
  data: {
    message: 'Hello Vue!'
  }
})

{{ message[0] }}
