  • Q2. Shallow copy vs deep copy
  • Ans. 

    Shallow copy only copies the references of nested objects, while deep copy creates new copies of nested objects.

    • Shallow copy creates a new object but does not create copies of nested objects.

    • Deep copy creates a new object and also creates copies of nested objects.

    • Shallow copy is faster and more memory efficient, but changes to nested objects affect both original and copied objects.

  • Q3. Arrow function vs Regular function
  • Ans. 

    Arrow functions are concise and do not bind their own 'this' value, while regular functions have their own 'this' value and can be used as constructors.

    • Arrow functions have a more concise syntax compared to regular functions.

    • Arrow functions do not have their own 'this' value, they inherit it from the parent scope.

    • Regular functions have their own 'this' value, which can be useful for object-oriented programming and cons

  • Answered by AI
  • Q4. Subject vs BehaviourSubject
  • Ans. 

    Subject vs BehaviourSubject in Angular

    • Subject is a basic observable that emits values to subscribers

  • Q6. Custom pipes and how to use it in html
  • Ans. 

    Custom pipes in Angular are used to transform data in templates.

    • Custom pipes are created using the @Pipe decorator in Angular.

    • To use a custom pipe in HTML, you need to include it in the declarations array of the NgModule.

    • You can pass parameters to custom pipes in HTML using the pipe symbol (|).

    • Example: {{ value | customPipe:param1:param2 }}

  • Answered by AI
  • Q7. What is ng-template, ng-content and ng-container
  • Ans. 

    ng-template, ng-content, and ng-container are Angular structural directives used for template rendering and content projection.

    • ng-template is used to define a template that can be rendered conditionally or multiple times.

    • ng-content is used for content projection, allowing the insertion of content from a parent component into a child component.

    • ng-container is a grouping element that doesn't interfere with styles or layo...

  • Answered by AI
  • Q8. Explain ForkJoin and parallel execution
  • Ans. 

    ForkJoin is an operator in Angular that allows for parallel execution of multiple observables.

    • ForkJoin combines the values from multiple observables and emits them as an array when all observables complete.

    • It waits for all observables to complete and then emits the combined result.

    • Example: forkJoin([observable1, observable2]).subscribe(result => console.log(result));

  • Answered by AI
  • Q9. Wildcard routes and it's syntax
  • Ans. 

    Wildcard routes in Angular allow for handling unknown routes and redirecting to a default route.

    • Wildcard route is denoted by '**' in the route configuration.

    • It is typically used at the end of the route configuration to handle unknown routes.

    • Example: { path: '**', redirectTo: '/404' }

  • Answered by AI

    • Use try-catch blocks to catch errors during API calls

    • Implement error handling logic in the catch block to handle different types of errors

    • Display user-friendly error messages to inform users about the issue
