Vuejs.org: Why official doc doesn't use method shorthands?

[sehyunchung]

The doc says:

computed: {
    // a computed getter
    reversedMessage: function () {
      // `this` points to the vm instance
      return this.message.split('').reverse().join('')
    }
  }

not

computed: {
    // a computed getter
    reversedMessage() {
      // `this` points to the vm instance
      return this.message.split('').reverse().join('')
    }
  }

I'm just curious and totally okay not using it but Isn't it just the same? And it's 2020 and pretty safe using ES2015. What's the reason behind this?

That's because Vue 2.x supports IE 11 and we want our examples in the doc to be working as-is everywhere.
