The wire service provisions an immutable stream of data to the component (To mutate the data, a component should make a shallow copy of the objects it wants to mutate) The @AuraEnabled annotation enables client-side and server-side access to an Apex controller method @AuraEnabled(cacheable=true) is obligatory to use @wire decorator https://developer.salesforce.com/docs/platform/lwc/guide/apex-wire-method.html https://developer.salesforce.com/docs/platform/lwc/guide/data-wire-service-about.html
