items.update(itemsArray => [itemsArray, …newItem]); ``` - The `mutate` method was removed from the `WritableSignal` interface and completely dropped from the public API surface. As an alternative please use the update method and make immutable changes to the object. Example before: ```t...
it resulted in no changes to the return type. Now the type would be narrowed, which might require updates to the application code that relied on the old behavior.
const value = signal(0); value.update(curr=> curr + 5); //类似于//value += 5; update 和 set 都是用来修改 value 的, 区别是 update 带有一个 current value 的参数,方便我们做累加之类的操作。 你要改成 set 也可以 value.set(value() + 5); 因为update 底层也是调用了 set 方法。 compute...

the array is empty([]), the item is deleted, otherwise the item is replaced by the items in the array. If the return value is not an array, the item remains unaffected, unless some updates were made to the item in the updater function. This can be thought of as in place update. ...
