What are the LWC lifecycle hooks?

LWC lifecycle hooks: constructor(): Called when the component is created. Do not access the DOM or child components here. Call super() first. connectedCallback(): Called when the component is inserted into the DOM. Safe to access the component's own DOM (not children yet). Good for data fetching, event subscription, and initialisation. renderedCallback(): Called after every render. Use for post-render DOM manipulation. Be careful of infinite loops (avoid state changes that trigger re-renders here). disconnectedCallback(): Called when the component is removed from the DOM. Use for cleanup (unsubscribing from message channels, clearing timers). errorCallback(error, stack): Error boundary — catches errors from child components. Only available on components acting as error boundaries.
