Route model binding is a technique that automatically injects model instances into route callbacks or controller methods based on the route parameters. This simplifies the process of retrieving model instances, as developers no longer need to manually retrieve models from the database using the route parameters.
Instead, Laravel automatically resolves the model instance based on the parameter name and type hinting in the route or controller method. This makes it easier to work with models in Laravel and reduces the amount of boilerplate code required to retrieve models based on route parameters.
