Pros and cons of SCSS (Sass) compared to CSS

 SCSS (Sass):


  1. Variables: SCSS allows you to declare variables, making it easy to reuse values throughout your stylesheets. This promotes consistency and reduces redundancy in your code.

  2. Nesting: SCSS allows for nested CSS rules, which can help to organize and structure your stylesheets in a more hierarchical way, resembling the HTML structure. This can improve readability and maintainability.

  3. Mixins: SCSS supports mixins, which are reusable blocks of styles that can be included in multiple selectors. This enables you to encapsulate common patterns or sets of styles, promoting code reusability and maintainability.

  4. Functions: SCSS includes built-in functions that allow for more advanced and dynamic stylesheet generation. These functions can perform calculations, manipulate colors, and more, providing greater flexibility in your stylesheets.

  5. Partials and Importing: SCSS supports the use of partials, which are separate files containing segments of CSS that can be imported into other SCSS files. This modular approach can help to organize your stylesheets into smaller, more manageable pieces.

  6. Extends: SCSS provides the @extend directive, which allows one selector to inherit styles from another selector. This can help to avoid code duplication and maintain a more DRY (Don't Repeat Yourself) codebase.

How many route guards are available in Angular 17?

Angular 17 Router Guards: A Concise Guide

In Angular 17, router guards have evolved to provide a more concise and modern approach, leveraging functional programming introduced in Angular v14.2. These guards facilitate fine-grained control over navigation, authentication, data resolution, and lazy loading of modules. Let's explore the six different router guards available in Angular 17:

1. CanActivateFn

  • Purpose: Determines if a route can be activated.
  • Logic: Returns a boolean, UrlTree, or an Observable/Promise resolving to one of these.
    • true: Navigation proceeds.
    • false: Navigation is blocked.
    • UrlTree: Redirection to a different route.
  • Use Cases:
    • Authentication checks (redirect to login if not authorized)
    • Role-based authorization
    • Prevent access to partially completed forms

How to write regular expressions?

Regular expressions, often abbreviated as regex or regexp, are sequences of characters that define a search pattern. They are incredibly powerful for searching, extracting, and manipulating text based on patterns. Here's a beginner-friendly introduction to regular expressions along with some examples:

1. Basic Matching:

  • .: Matches any single character except newline.
    • Example: c.t matches "cat", "cot", "cut", etc.
  • [ ]: Matches any single character within the brackets.
    • Example: [aeiou] matches any vowel.
  • [^ ]: Matches any single character not within the brackets.
    • Example: [^aeiou] matches any non-vowel.
  • |: Alternation, matches either the expression before or after the |.
    • Example: cat|dog matches "cat" or "dog".

What is Microsoft Teams?

 Microsoft Teams is a unified communication and collaboration platform that combines workplace chat, video conferencing, file storage, and application integration. It is part of the Microsoft 365 suite of products and is available as a desktop app, web app, and mobile app.

Teams allows users to create and join teams, which are groups of people who work together on projects or tasks. Teams can be public, private, or external (meaning they include people from outside of your organization).

Within a team, users can chat, make video calls, share files, and collaborate on documents in real time. Teams also integrates with other Microsoft 365 apps, such as SharePoint, OneDrive, and OneNote, making it easy to access and share files from those apps.
