Before using LiveWire, JavaScript was always the language used for both frontend and backend development. When choosing a framework, one of the most important factors to consider is validation.
Validation is a crucial and time-consuming aspect of development. It needs to be performed on the frontend, backend, and when modifying the database through input, update, or delete operations. In some cases, the validation process may be performed twice. Typically, the backend performs validation using the same language.
In liveiwre word some button action and alpine @click action be clicked, livewire 3 update (ajax) is different your think.

livewire window.livewire.find eloquent collection https://github.com/livewire/livewire/issues/1641?fbclid=IwAR0uHylkj-1vg8p5jUoBgPYfuAYsWnBhgp6EK2bJcBce8ze-tdtAa8ElLNY#issuecomment-736146468 Eloquent Collection data won't be made available to the front end unless you have the collection properties specified in the $rules array as the contents are models, so the same conditions apply to it as apply to just a single model property. This is for security reasons so the whole collection and all properties aren't just sent to the front end.
