list.md simplify example

[Alex-Sokolov]

Maybe simplify a little example in lists?

Now backticks used only in two places:

• installation.md (line 93)

// this requires the compiler
new Vue({
  template: `<div>{{ hi }}</div>`
})

// this does not
new Vue({
  render (h) {
    return h('div', this.hi)
  }
})

• components.md (line 573)

Vue.component('currency-input', {
  template: `
    <span>
      $
      <input
        ref="input"
        v-bind:value="value"
        v-on:input="updateValue($event.target.value)">
    </span>
  `,
  props: ['value'],
  methods: {
    // Instead of updating the value directly, this
    // method is used to format and place constraints
    // on the input's value
    updateValue: function (value) {
      var formattedValue = value
        // Remove whitespace on either side
        .trim()
        // Shorten to 2 decimal places
        .slice(0, value.indexOf('.') + 3)
      // If the value was not already normalized,
      // manually override it to conform
      if (formattedValue !== value) {
        this.$refs.input.value = formattedValue
      }
      // Emit the number value through the input event
      this.$emit('input', Number(formattedValue))
    }
  }
})
