Introduction to algorithm and different types of algorithms

An algorithm can be defined as a finite step by step instructions to perform an operation.
In computer science, an algorithm is defined as a finite step by step instructions to solve a computational problem efficiently.
Algorithms are important as they help solve computational problems efficiently, make programs run faster, and improve problem-solving skills.
Examples of different types of algorithms include brute force approach, recursive approach, dynamic programming, backtracking algorithm, greedy approach, and divide and conquer.

Dynamic forms with discriminatedUnion and React Hook Form

Form validation is a crucial aspect of modern web applications.
This article explains how to use both Zod and RHF to validate dynamic forms, including those with complex structures such as payment methods.
DiscriminatedUnion is an advanced typing technique used to model objects with different structures but sharing a common discriminating field.
Each payment method specific rules that must not interfere with each other interfere.
Allows new types to be added easily, ensuring that any invalid values are detected at validation time.
React Hook Form makes it easy to manage forms while remaining high-performance and flexible.
GetErrorsByPaymentType() method helps to separate the errors with their fields using their payment types.
The article provides an example of payment form validation using discriminatedUnion and React Hook Form.
Zod and RHF dynamically adapt validation according to the type field, simplifying the logic in the form.
This utility type can be used in many ways, and it is highly recommended in dealing with validation and other scenarios.

JavaScript Testing and Automation: Ensuring Quality and Reliability in Your Code

JavaScript testing and automation are essential practices for ensuring the quality, functionality, and performance of web applications.
Testing is critical in software development as it ensures that code behaves as expected, detects bugs early, and makes maintenance easier.
JavaScript testing typically focuses on verifying different types of behavior in applications including functional testing, integration testing, and end-to-end testing.
Popular JavaScript testing frameworks and libraries include Jest, Mocha, Chai, Jasmine, Cypress, Karma, Puppeteer, and TestCafe.
JavaScript automation tools include Webpack, Gulp, Grunt, CI/CD pipelines, and Selenium.
Best practices for JavaScript testing and automation include writing tests early, automating repetitive tasks, using code coverage, and keeping tests isolated.
Unit tests are isolated and not dependent on external resources like databases or APIs. It makes tests faster and more reliable.
Automated testing saves time and boosts confidence in the application's stability and performance.
JavaScript testing and automation are indispensable for building high-quality web applications.
By adopting testing practices and utilizing the right tools, developers can catch bugs early and deliver a better user experience.

GitHub Compliance – All You Need To Know

GitHub has security and compliance regulations companies need to deal with as a set of shared responsibility models.
The organizations that use GitHub Enterprise can grant different access permissions to their employees, and customize a set of permissions for teams and users using role-based access control (RBAC).
GitHub is compliant with GDPR regulations and provides its customers with the ability to access and control the information it collects and processes about them.
The compliance requirements depend on the industry, and the assurance that all the business processes and the sensitive data, including customer’s data, are secure and won’t be accessed by any unauthorized party.
GitHub performs backup of its entire system and all the data users have on the platform, but organizations should have an account-level backup of their data in place for all repositories and metadata.
The organization should have a response to any disaster scenario - the entire GitHub service outage or the organization’s GitHub environment failure.
GitHub has implemented major compliance regulations like AWS, Data Privacy, GDPR, SOC 1 and SOC 2, FedRAMP LI-Saas Authorization to Operate (ATO), Cloud Security Alliance, and ISO/IEC 27001:2013.
Organizations that use Git must take measures to protect their source code and adopt the right strategies and practices to boost their GitHub repositories and metadata security.
The majority of compliance standards focus on areas like metadata categorisation, access control, permissions, source code integrity, auditing and review of access, backup, and recovery.
GitHub Backup plays one of the leading roles and is one of the main requirements for GitHub compliance.

Unlock Angular's Full Potential With These 5 RxJS Operators

RxJS operators such as map, filter, and mergeMap are commonly used for transforming and filtering data streams.
Partition helps to handle different types of data in separate streams based on the predicate.
CombineLatestWith is perfect for synchronizing multiple streams in real-time.
Audit ensures precise throttling without losing the latest value.
The expand operator can be used for recursive operations like recursive API calls or tree traversals.
The groupBy operator splits an observable into multiple observables, grouped by a specified key.
Using these lesser-known operators can make your code more efficient and elegant.
Combine partition with expand for advanced logic.
Choose operators based on your data flow requirements.
Start experimenting with these examples, and watch your Angular applications become more dynamic and powerful!
