Possible disadvantages of RegExr

  • Limited Offline Use
    Since RegExr is a web-based application, it requires an internet connection, limiting its utility for users who need to work offline.
  • Learning Curve
    While the tool is user-friendly, users still need to have a foundational understanding of regular expressions to use RegExr effectively.
  • Performance Issues
    For extremely large inputs or very complex regular expressions, the tool may experience performance lags or slowdowns.
  • Limited Advanced Features
    RegExr may lack some advanced features found in more specialized or professional regex tools, such as integration with development environments or extensive scripting capabilities.
  • Privacy Concerns
    Users inputting sensitive data need to be cautious, as the web-based nature of the tool could raise privacy or data security concerns.

MobX features and specs

  • Simplicity
    MobX allows developers to manage state in a simple and straightforward manner. Its API is minimal and doesn't impose the rigid structure that other state management libraries might require.
  • Reactivity
    The library provides powerful reactive state management, meaning that it automatically updates the UI when the underlying data changes, minimizing boilerplate code.
  • Performance
    MobX optimizes re-rendering by tracking dependencies precisely, making updates efficient and reducing unnecessary renders.
  • Integration
    MobX can easily integrate with React and other JavaScript frameworks, making it flexible for use in various types of projects.

Possible disadvantages of MobX

  • Learning Curve
    While MobX is straightforward for simple use cases, understanding its reactivity and decorators might be challenging for beginners.
  • Scalability Concerns
    For very large applications, the unstructured nature of MobX might lead to spaghetti code if not managed properly, making it harder to maintain.
  • Less Community Support
    Compared to other state management libraries like Redux, MobX has a smaller community, which could mean fewer resources for troubleshooting and learning.
  • Loose Structure
    The lack of rigid structure, while contributing to simplicity, can result in code that is harder to manage, especially in larger applications where a more organized approach might be beneficial.

  • Learning Perl - Regular Expressions
    Use Online Tools: There are many online regex testers and visualizers that can help you see how your patterns match against sample text. These tools often provide explanations for each part of the regex. I personally use https://regexr.com/. - Source: dev.to / 2 days ago
  • The importance of the environment in Regex pattern matching
    However - here it becomes weird - when testing the original regex rule (the first one, without the \u00A0 part) on the same string in an interactive visualiser (https://regexr.com/ for instance), there is a match:. - Source: dev.to / 8 months ago
  • Ask HN: How did you learn Regex?
    Learned regex in the 90's from the Perl documentation, or possibly one of the oreilly perl references. That was a time where printed language references were more convenient than searching the internet. Perl still includes a shell component for accessing it's documentation, that was invaluable in those ancient times. Perl's regex documentation is rather fantastic. `perldoc perlre` from your terminal. Or... - Source: Hacker News / 10 months ago
  • Ask HN: How did you learn Regex?
    I read a lot on https://www.regular-expressions.info and experimented on https://rubular.com since I was also learning Ruby at the time. https://regexr.com is another good tool that breaks down your regex and matches. One of the things I remember being difficult at the beginning was the subtle differences between implementations, like `^` meaning "beginning of line" in Ruby (and others) but meaning "beginning of... - Source: Hacker News / 10 months ago

    Mostly building things that needed complex RegEx, and debugging my regular expressions with https://regexr.com/. - Source: Hacker News / 10 months ago

    States can also be organized in some central places (aka. stores). You can use Tini Store (very simple, ~50 lines) or other state management solutions such as MobX, TinyX, ... - Source: dev.to / about 1 year ago
  • Episode 24/13: Native Signals, Details on Angular/Wiz, Alan Agius on the Angular CLI
    Similarly to Promises/A+, this effort focuses on aligning the JavaScript ecosystem. If this alignment is successful, then a standard could emerge, based on that experience. Several framework authors are collaborating here on a common model which could back their reactivity core. The current draft is based on design input from the authors/maintainers of Angular, Bubble, Ember, FAST, MobX, Preact, Qwik, RxJS, Solid,... - Source: dev.to / about 1 year ago
  • React State Management in 2024
    Mutable-based: leverages proxy to create mutable data sources which can be directly written to or reactively read from. Candidates in this group are MobX and Valtio. - Source: dev.to / over 1 year ago
  • Show HN: Cami.js – A No Build, Web Component Based Reactive Framework
    Looks good! FWIW I always felt the observable pattern much more intuitive than the redux/reducer style. Something like https://mobx.js.org/ Things get hairy in both, but redux pattern feels so ridiculously ceremonially to effectively manage a huge global state object with a false sense of "purity". Observables otoh say "fuck it, I'm mutating everything, do what you want with it". - Source: Hacker News / over 1 year ago
  • React Redux
    It's important to note that Redux is just one of many options for global state management in a React application. Other popular options include MobX and the React context API.context API](https://reactjs.org/docs/context.html). - Source: dev.to / over 2 years ago
