Vue lifecycle hooks are a collection of predefined methods that are invoked at various points during the lifespan of a Vue component. These hooks give programmers the option to execute particular code at specific times throughout the mounting, updating, and destroying of Vue components. These lifecycle hooks let developers manage how their components behave and carry out operations like data initialization, API requests, and DOM updates in response to component state changes. It's essential to comprehend the Vue lifecycle hooks if you want to create apps that are reliable and well-organized.
