Filter Array Of Objects By Index

I want to filter array of objects by index.

• {{list.note} &l

Solution 1:

I think this will works

deleteNote(i) {
  this.lists = this.lists.filter((_, index) => index !== i);
}

Solution 2:

You need to use second argument to the filter function.

let arr = this.lists.filter( (item, index) =>  
    item.note !== this.lists[index]
);
this.lists = arr;

Here is MDN docs for Filter

Hope this helps!

Solution 3:

By the looks of it, you want to remove an item by index?

deleteNote(i) {
  this.lists.splice(i, 1);
}

The above snippet should modify the existing array and remove one element at the desired index.

MDN: Array.prototype.splice()
