I have data stored in my VueJS component as a list, and it is rendered to the DOM using a v-for loop that iterates through each item in the array. I have a button that removes an item from the array, and now I am working on making the add button add back one item at a time if that item is not already in the array.
addItem: function(){
for (item in this.array){
if (item !== item){
this.array.push(item)
}else{
continue
}
}
},It appears that your if statement lacks clarity.
Your code does not clearly indicate where the item you wish to add to the array originates from. Perhaps it should be passed as a function argument.
In any case, if you intend to add an item to an array only if it is not already present in the array, you can utilize Array.prototype.includes.
