Lazy loading in Angular allows for loading modules only when they are needed, improving performance.
Lazy loading is achieved by using the loadChildren property in the route configuration.
Modules are loaded asynchronously when the user navigates to a route that requires them.
Lazy loading helps reduce the initial bundle size and improve the app's loading time.
Example: { path: 'admin', loadChildren: () => import('./admin/

- Q2. What is hoisting in javascript?
- Ans.
Hoisting in JavaScript is the behavior where variable and function declarations are moved to the top of their containing scope during the compilation phase.
Variable declarations are hoisted to the top of their scope, but not their assignments.
Function declarations are fully hoisted, meaning they can be called before they are declared.
Hoisting can lead to unexpected behavior if not understood properly.
