JavaScript React immutability helper - set new value at index in array react immutability helper update,react immutability helper,react immutability helper

Is there any way I can set value of array in specific index with React imutability helper ?

For example something like this:

   const newState = update(this.state , {
        open[8]:{$set: false}
    })
    this.setState(newState);

or do I have to deep clone that array using JSON and then set new value at specific index and then use react imutability helper to update state?
