Vue Js Array Shift Method
Vue Js Array Shift Method: In Vue.js, the shift() method is used to remove the first element from an array and return that removed element. The original array is modified by the shift() method, and the shifted element is returned as the result. This method can be used to remove the element at index 0 in an array-like object and then iterate over the updated array. For example, if you have an array in Vue.js and you want to remove the first element from it and then iterate over the updated array, you can use the shift() method to achieve this functionality.
