JavaScript features and specs

• Wide Browser Support
  JavaScript is supported by all modern web browsers without the need for any plugins, making it highly versatile for client-side scripting.
• Asynchronous Programming
  JavaScript supports asynchronous programming with features like callbacks, Promises, and async/await, which helps in efficiently handling tasks such as HTTP requests.
• Rich Ecosystem and Libraries
  The JavaScript ecosystem includes a vast amount of libraries and frameworks like React, Angular, Vue, and Node.js, which streamline development processes.
• Community Support
  JavaScript has a large and active community, providing extensive resources, documentation, and forums for troubleshooting and development advice.
• Event-Driven
  The language is inherently event-driven, making it suitable for developing interactive web applications that react to user inputs.
• Full-Stack Development
  With the advent of Node.js, JavaScript can be used for both client-side and server-side development, enabling full-stack development using a single language.

Possible disadvantages of JavaScript

• Security Issues
  Being an interpreted language that runs in the browser, JavaScript code is visible to the user, making it susceptible to security risks such as Cross-Site Scripting (XSS).
• Browser Compatibility
  While JavaScript itself is widely supported, different browsers may implement JavaScript functions and standards differently, leading to compatibility issues.
• Performance
  JavaScript is generally slower than compiled languages such as C++ or Java. Heavy computations can lead to performance bottlenecks.
• Single Inheritance
  JavaScript uses prototypal inheritance instead of classical inheritance, which can be confusing for developers coming from object-oriented programming backgrounds.
• Dynamic Typing
  JavaScript's dynamic typing can lead to runtime errors that are hard to debug, as variable types are checked at runtime rather than during compilation.
• Fragmentation
  The ecosystem has many competing libraries, frameworks, and tools, which can make it overwhelming for developers to choose the right technologies for their projects.

Possible disadvantages of Tableau Prep

• Limited Advanced Transformations
  While Tableau Prep offers many useful tools, it lacks some advanced data transformation capabilities found in more specialized ETL (Extract, Transform, Load) tools.
• Performance Issues with Large Datasets
  Users may experience performance slowdowns when working with extremely large datasets, affecting overall efficiency and user experience.
• Steep Learning Curve for Complex Tasks
  Although its interface is user-friendly for simple tasks, more complex data preparation processes still require a deeper understanding, making the learning curve steeper for advanced functionalities.
• Cost
  Tableau Prep is a paid product, and the cost could be a barrier for small businesses or individual users who might not have the budget for a subscription.
• Limited Custom Scripting
  Does not provide extensive support for custom scripting, limiting the flexibility for users who need highly customized data transformation processes.
