I have a state in my class component:

this.state = {
  todos: [ {0: "Wake up"}, {1: "Have breakfast"}, {2, "Have lunch}, ... ]
}

How can I remove an specific element from todos without mutating the array itself? I then want to set todos to a new array without that element.

Any help is appreciated as I am new to React!

either you mutate or get a new object. there is no deleting without mutating. – Nina Scholz Jan 30 '22 at 11:24
```this.setState(state=> state.filter(item=> !item.0)``` make use of filter to remove a particular element from an array. – ngprnk Jan 30 '22 at 11:50
