The component lifecycle in Lightning Web Components includes phases like creation, rendering, update, and destruction. Key lifecycle hooks are used to execute code at different stages. constructor() is called when a component instance is created. connectedCallback() is invoked when a component is inserted into the DOM, ideal for initialization tasks. renderedCallback() is called after a component renders and re-renders, suitable for post-render logic. disconnectedCallback() occurs when a component is removed from the DOM, useful for cleanup tasks. Understanding these lifecycle hooks is essential for managing resources, handling initialization, and updating the DOM in response to data changes.
