I very new in vue, how can mylist random, can get the same value from somerandom

export default {
  data () {
    return {
        somerandom:"foo",
        mylist:{
            random: this.somerandom
        }

You can try with computed property:

new Vue({
  el: '#demo',
  data () {
    return {
        somerandom:"foo",
        mylist:{
            random: ''
        }
    }
  },
  computed: {
    rand() {
      return this.mylist.random = this.somerandom
    }
  }
})

Vue.config.productionTip = false
Vue.config.devtools = false

<div id="demo">
    <p>{{ rand }}</p>
</div>

model init an object with value. can set value by default or run func after computed or mounted

data() {
    return {
      somerandom: '',
      someOther: [],
    }
},
computed: {
    useRandom() {
        this.somerandom = this.rand();
    }
},
methods: {
    rand(){
       return 'random';
    }
}
