props in readonly vue js code example

Example 1: vue prop string or number

props: {
        users_count: {
            type: [Number, String],
            required: true
        }
    },

Example 2: 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>
