How to change a Item value of a state.

for example, I have a list state like this:
```js
this.state = {
    list:[1,2,3,4,5]
}
```

How can I change the value of the first item of list from 1 to 0? 

I usually use like this but I don't believe that is the best way.
```js
var temp = this.state.list;
temp[0] = 0;
this.setState({ list : temp});
```

Please who can tell me is there any better way to do this ?
