Vue get first occurrence of empty string in array:In Vue, you can use the indexOf method of an array to find the index of the first occurrence of an empty string. The indexOf method returns the index of the first element in the array that matches the specified value. If the value is not found, it returns -1.

To use the indexOf method to find the index of the first occurrence of an empty string, you can call the method on the array and pass an empty string as the argument. If the array contains an empty string, the method will return the index of its first occurrence. If the array does not contain an empty string, the method will return -1. This can be useful when working with arrays of strings and needing to identify the position of empty strings for further manipulation or filtering.

What is the best way to retrieve the index of the first occurrence of an empty string in a Vue.js array?

The code defines a Vue instance with an array arr containing several strings, some of which are empty. It also has a result property which is initially empty. The mounted() hook is used to set the result property to the index of the first occurrence of an empty string in the arr array using the indexOf() method. The resulting index is then displayed in the template using Vue’s v-if directive.

                    arr: ['Vue js', 'React Js','' ,'Angular Js','', 'Express Js', 'Node Js'],
                    result: ''
                };
            },
            mounted() {
                this.result = this.arr.indexOf('')
            }
        })
</script>
