How to access props in vue code example

Example 1: vue get props into data

props : {
        users : Array,
        currentuser: Number,
        todoId : Number
    },
    mounted() {
        this.current = this.currentuser
    },
    data(){
        return{
            current: null
        }

Example 2: vue js default prop

props: {
  name: {
    type: String,
    default: 'John Doe'
  }
}

Example 3: vuejs components props pass array

<!-- Even though the array is static, we need v-bind to tell Vue that -->
<!-- this is a JavaScript expression rather than a string.            -->
<blog-post v-bind:comment-ids="[234, 266, 273]"></blog-post>

<!-- Dynamically assign to the value of a variable. -->
<blog-post v-bind:comment-ids="post.commentIds"></blog-post>

Example 4: vuejs accessing props from data

data: function() {
  var theData = {
    somevar: this.messageId,
    // other object attributes
  }

  return theData;
}
