Vue Js change or update first value of array
Vue Js change or update first value of array:In Vue.js, you can change or update the first value of an array using the
splice
method. First, you need to access the array within your Vue component's data. Then, you can use the
splice
method on that array, passing the index of the element you want to update as the first argument, the number of elements to remove as the second argument (which would be 1 in this case), and the new value as the third argument. This will replace the first element of the array with the new value, effectively updating it.

How can I change or update the first value of an array in Vue.js?
This Vue.js code demonstrates how to change or update the first value of an array.
The code initializes a Vue app with an array called myArray
containing [1, 2, 3, 4, 5]
. When the "Update First Value" button is clicked, the updateFirstValue
method is triggered.
This method uses the splice
method to replace the first element of myArray
with the newValue
parameter (in this case, 10). As a result, the displayed array will be [10, 2, 3, 4, 5]
.
