Possible disadvantages

  • Limited Advanced Features
    While great for beginners, advanced typists may find the exercises less challenging and lacking in complexity.
  • Advertisements
    The free version includes ads, which can be distracting for some users. An ad-free experience requires a premium subscription.
  • No Offline Mode
    Keybr requires an internet connection to function, which can be inconvenient for users looking for offline typing practice.
  • Repetitive Exercises
    Some users may find the exercises repetitive over time, potentially reducing engagement and motivation.
  • Asynchronous Programming Model
    RxJS allows you to work with asynchronous data streams with ease, enabling you to handle events, Ajax requests, and other asynchronous operations more effectively.
  • Composability
    RxJS operators enable developers to compose complex asynchronous operations concisely. This provides greater flexibility and power over handling streams of data.
  • Functional Programming Paradigm
    By using a functional programming approach, RxJS promotes cleaner and more predictable code. It encourages immutability and side-effect-free functions, enhancing code maintainability.
  • Rich Operator Set
    RxJS has a comprehensive set of operators, which allows developers to transform, combine, and filter data streams in various ways without needing to write a lot of boilerplate code.
  • Community and Ecosystem
    With its active community and extensive ecosystem, RxJS provides robust support, an abundance of learning resources, and numerous integrations with other libraries and frameworks.

Possible disadvantages

  • Steep Learning Curve
    For developers unfamiliar with reactive programming concepts or functional programming, understanding RxJS can be challenging, potentially leading to difficulty in adopting it.
  • Overhead for Simple Tasks
    Using RxJS for simple asynchronous tasks might add unnecessary complexity compared to native JavaScript promises or async/await due to its powerful abstractions.
  • Bundle Size
    In certain circumstances, incorporating RxJS might lead to increased bundle sizes, which can be a concern for web performance if not managed properly.
  • Complex Debugging
    RxJS introduces a level of abstraction that can make debugging more complex, especially when dealing with multiple combined and transformed data streams.
  • Performance Overhead
    While RxJS is powerful, its generalized approach to handling asynchronous stream processing can introduce performance overhead if not used judiciously.

    Try a small change and sometimes a drastic one (like dropping a column or row) and mash keybr.com and monkeytype.com until it feels natural, or not then revert. And if I revert I often try again a few weeks later... Source: almost 3 years ago
