v-for Directive in Vue.js

Last Updated : 25 Jun, 2020

v-for directive is a Vue.js directive used to loop over a data usually an array or object. First, we will create a div element with id as app and let's apply the v-for directive to an element with data. Now we will create this data by initializing a Vue instance with the data attribute containing the value.

Syntax:

v-for="data in datas"

Parameters: This function accepts data which is either an array or object over which we will loop over. Example: This example uses Vue.js to loop over an array with v-for.
