necessary, as it may lead to excessive re-renders and performance issues.

You can pass a selector function as the first parameter of use to only subscribe to a subsect of that state.

This is useful for optimizing performance eg for long lists.

const activeTodo=todosStore.use((todos)=> {

returntodos.find((todo)=>todo.id===activeTodoId);

});

You can use the`get` and`use` methods to access deeply nested state properties.

Computed properties, defined using the`computed` method, can also be accessed using`get` and`use`. However, they cannot be directly modified using`set` or`assign`.

Computed properties, defined using the`computed` method, can also be accessed using`get` and`use`.

const fullName=userStore.fullName.get();

const fullName=userStore.fullName.use();

const countStore=store({ count:0 })

.computed((store)=> ({

doubled: {

read: ()=>store.count.use()*2,

write: (value:number)=>store.count.set(value/2),

},

}))

.actions((store)=> ({

increment() {

store.count.set(store.count.get()+1);

},

decrement() {

store.count.set(store.count.get()-1);

},

}));

Note: inputs are optional for both read/write and strongly typed.
