items: {JSON.stringify(object.items)}
``` ...the array being pushed to when the button is first clicked is the `[]` on the right-hand side of the assignment, but the resulting value of `object.array` is an empty state proxy. As a result, the pushed value will be discarded. You can fix this by separating it into two statements: ```js let object = { array: [0] }; // ---cut--- function add() { object.array ??= []; object.array.push(object.array.length); } ``` ### binding_property_non_reactive ``` `%binding%` is binding to a non-reactive property ``` ``` `%binding%` (%location%) is binding to a non-reactive property ``` ### console_log_state ``` Your `console.%method%` contained `$state` proxies. Consider using `$inspect(...)` or `$state.snapshot(...)` instead ``` When logging a [proxy](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Proxy), browser devtools will log the proxy itself rather than the value it represents. In the case of Svelte, the 'target' of a `$state` proxy might not resemble its current value, which can be confusing. The easiest way to log a value as it changes over time is to use the [`$inspect`](https://svelte.dev/docs/svelte/$inspect) rune. Alternatively, to log things on a one-off basis (for example, inside an event handler) you can use [`$state.snapshot`](https://svelte.dev/docs/svelte/$state#$state.snapshot) to take a snapshot of the current value. ### event_handler_invalid ``` %handler% should be a function. Did you mean to %suggestion%? ``` ### hydration_attribute_changed ``` The `%attribute%` attribute on `%html%` changed its value between server and client renders. The client value, `%value%`, will be ignored in favour of the server value ``` Certain attributes like `src` on an `
