Exploring Object-Oriented Programming (OOP) in JavaScript

JavaScript provides robust support for OOP through its prototypes, ES6 classes, and modern enhancements.
In JavaScript, an object is a collection of key-value pairs.
Classes are the blueprints for creating objects and encapsulate data and behavior.
Encapsulation bundles data and methods together while restricting direct access to some components.
JavaScript uses public, private, and protected members to achieve encapsulation.
Inheritance allows one class to inherit properties and methods from another class.
Polymorphism enables overriding methods from parent to subclass to provide a specific implementation.
Abstraction allows you to expose only essential details while hiding implementation complexities.
JavaScript's prototype-based language allows every object to have an internal link to another object called its prototype.
Object composition is an alternative to inheritance, which helps avoid the complexities of deep inheritance hierarchies.

2182. Construct String With Repeat Limit

Given a string s and an integer repeatLimit, construct a new string repeatLimitedString using the characters of s such that no letter appears more than repeatLimit times in a row.
Return the lexicographically largest repeatLimitedString possible.
We use a greedy approach to prioritize lexicographically larger characters while ensuring that no character exceeds the repeatLimit consecutively.
The approach uses a priority queue (max heap) to process characters in lexicographically descending order and ensures that no character appears more than the repeatLimit times consecutively.
We use all of the characters from s to construct the repeatLimitedString.
The time complexity of the solution is O(n + 26 log 26) ≈ O(n)and the space complexity is O(26) for the frequency array and O(26) for the heap.
This implementation works efficiently within the constraints.
Test cases: echo repeatLimitedString("cczazcc", 3) . "\n"; // Output: "zzcccac" and echo repeatLimitedString("aababab", 2) . "\n"; // Output: "bbabaa".
Edge cases: When s contains only one unique character, when repeatLimit is equal to 1 or When all characters in s are unique.

Issues Adopting Swift Testing

Migrating from XCTest to Swift Testing is straightforward for the most part, but it sometimes faces issues that are not easy to resolve.
Swift Testing has no equivalent to XCTAssertEqual(_:_:accuracy:).
Implicitly Unwrapped Optionals are handled a bit better in Swift Testing but it still requires their use.
Swift Testing allows only one confirmation to be awaited at a time and does not run the run loop while waiting.
Parallel Tests run in the same process with Swift Testing, leading to issues with global state.
Using task-local properties seems to be the solution, but issues such as deployment targeting and concise setting of task-local values while setting up tests arise.
Conditional compilation errors can arise when using Swift Concurrency only during testing.
Assignments in setUpWithError() are not possible with Swift Testing, as @TaskLocal can only be used with closures.
Workarounds such as assigning values to properties in every test method or creating a hook like in XCTest are viable but can be burdensome.

How to use tokens in design systems?

Design tokens store specific styles or settings you can reuse within a design system.
Design tokens can be organized and well documented, facilitating visual consistency.
They encourage reasoning, maintainability, and reusability of design systems, leading to quicker production times and easier scalability.
Design variables (tokens) are handed off to developers so they can leverage the same benefits as designers.
Design tokens are stored in a transferable, platform-agnostic format, allowing them to be easily imported into any number of platforms.
Design tokens can be used to store values such as colors, spacings, typographic properties, and settings. They fit into four design variable categories in Figma.
To create a design token, you simply need to click on the Open variables icon, then create a variable and assign a value.
It's important to establish a naming convention and to document your design variables/tokens.
Using plugins like Style Dictionary and Tokens Studio can improve collaboration between designers and developers with Figma design tokens.
Design tokens facilitate consistency, maintenance, and synchronization of multi-platforms, making them an excellent tool for designers and developers to use in design systems.

Is the setState operation an async operation in react? + solution

The setState operation in React is asynchronous, meaning that it does not immediately update the state.
React batches multiple setState calls to optimize rendering performance.
Trying to access the state immediately after calling setState may not give you the updated state.
To handle logic that depends on the updated state, you can use the callback function provided by setState or functional updates.

Spring Boot @requestmapping To Serve A zip File

Serving a zip file from a Spring Boot application is a common requirement in modern web applications.
A Spring Boot @requestmapping can be used to serve a zip file.
The code example for serving zip files involves adding multiple dependencies to the pom.xml file in the project.
The example also includes creating a text file named example.txt to the src/main/resources directory, which contains the content that should appear in the zip file as a single file entry.
The @RestController annotation makes the UnifiedZipController class a Spring MVC controller capable of handling HTTP requests.
The UnifiedZipController class provides multiple endpoints for serving zip files with different functionalities.
Endpoints created include getZipAsByteArray(), getZipAsStream(), getZipWithCompression(), and getPasswordProtectedZip().
The application.properties file is used in Spring Boot applications to define configuration settings.
To run the Spring Boot application, ensure that you have Maven installed.
