Vue Js Get current array index position:In Vue.js, you can obtain the current array index position by utilizing the v-for directive. This directive has an optional second argument that denotes the current index. By accessing this index, you can determine the present position within the array. This feature enables you to manipulate or display data dynamically based on its position in the array, offering flexibility and control in Vue.js applications.
How can you retrieve the current index position of an element in an array using Vue js?
In the given Vue.js code, the v-for directive is used to loop through the items array. For each item in the array, the index of the current item is also available.
The :key attribute is used to provide a unique identifier for each item in the loop. Inside the loop, the index and the item are displayed using interpolation within double curly braces.
The index represents the current position of the item in the array, while the item variable holds the value of the item at that position.
