mypy logo mypy

Mypy is an experimental optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing.

Typescript logo Typescript

TypeScript allows developers to compile a superset of JavaScript to plain JavaScript on any browser, host, or operating system.

mypy features and specs

  • Static Type Checking
    Mypy provides static type checking for Python code, allowing developers to detect type errors during development rather than at runtime.
  • Improved Code Quality
    By catching type errors early, Mypy helps ensure code correctness and maintainability, leading to improved overall code quality.
  • Better Documentation
    Mypy's type annotations serve as a form of documentation, making it easier for developers to understand the expected types of function parameters and return values.
  • Easy Integration
    Mypy can be easily integrated with existing Python projects incrementally, allowing teams to adopt type checking gradually.
  • Support for Python 3 Typing
    Mypy supports Python 3's type hinting syntax, making it a natural fit for modern Python codebases.

Possible disadvantages of mypy

  • Partial Support for Python Features
    Mypy may not fully support some dynamic features of Python, leading to limitations in its type-checking capabilities for certain code patterns.
  • Initial Learning Curve
    Developers unfamiliar with type annotations or static type checking may face a learning curve when first adopting Mypy in their projects.
  • Additional Code Overhead
    Mypy requires additional type annotations in the code, which can add to the overall codebase size and require extra effort to maintain.
  • Performance Overhead
    While Mypy itself does not affect runtime performance, running type checks during development can introduce additional processing time.
  • Incompatibility with Some Libraries
    Certain third-party libraries may not provide type stubs or may not be fully compatible with Mypy's type checking, requiring developers to create custom stubs.

Typescript features and specs

  • Static Typing
    Typescript adds optional static typing to JavaScript, which allows for early error detection and better IntelliSense support.
  • Improved Code Quality
    The type system encourages developers to write more robust and maintainable code by enforcing the definition of types.
  • Enhanced IDE Support
    Most modern IDEs offer better code navigation, autocompletion, and refactoring tools for TypeScript due to its type information.
  • Compatibility
    TypeScript is a superset of JavaScript, meaning existing JavaScript code is valid TypeScript, and it can interoperate with JavaScript libraries.
  • Scalability
    TypeScript’s type system makes it easier to manage and scale large codebases, improving team collaboration.
  • Community and Ecosystem
    A large and growing community provides a wealth of resources, libraries, and tools tailored to TypeScript development.

Possible disadvantages of Typescript

  • Learning Curve
    Developers coming from a JavaScript background may need time to familiarize themselves with TypeScript concepts and syntax.
  • Build Step Requirement
    TypeScript code needs to be compiled to JavaScript, adding a build step to the development workflow.
  • Overhead
    The additional type annotations can lead to more verbose code, which may be seen as unnecessary overhead in smaller projects.
  • Tooling and Configuration
    Setting up TypeScript can sometimes be complex, requiring additional configuration for projects and integrations with various build tools.
  • Slower Iteration Speed
    The compilation process can slightly slow down the development cycle compared to working directly with JavaScript.
  • Strictness
    TypeScript’s strict type checks can sometimes be limiting, requiring workarounds or more complex type definitions.

Top 5 Most Liked and Hated Programming Languages of 2022
TypeScript is an open-source programming language that is here to beat the shortcomings of JavaScript. Yet another remarkable feature of this programming language that is worth a mention is that the TypeScript code converts to JavaScript. The ability of this language to understand JavaScript and use type inference to give the user great tooling without additional code is...

  • Java in the Small
    I've always admired many of Java's features, but let's not act like the reason for using Java for scripting is the pitfalls of Python. It's just because of an underlying preference for Java. 1. https://mypy-lang.org/. - Source: Hacker News / 5 months ago
  • Moving your bugs forward in time
    ‍I’m not here to tell people which languages they should love. But if you do find yourself writing production code in a dynamically typed language like Python, Ruby, or JavaScript, I would give serious consideration to opting into the type-checking tools that have become available in those ecosystems. In Python, consider requiring type hints and adding mypy checks to your CI to move your type safety bugs forward... - Source: dev.to / about 1 year ago
  • Embracing Modern Python for Web Development
    Mypy is "an optional static type checker for Python that aims to combine the benefits of dynamic (or "duck") typing and static typing". As Python is dynamically typed, Mypy adds an extra layer of safety by checking types at compile time (based on type annotations conforming to PEP 484), catching potential errors before runtime. - Source: dev.to / over 1 year ago
  • A Tale of Two Kitchens - Hypermodernizing Your Python Code Base
    Mypy stands as an essential static type-checking tool. Its primary function is to verify the correctness of types in your codebase. However, manually annotating types in legacy code can be laborious and time-consuming. - Source: dev.to / over 1 year ago
  • Lua: The Little Language That Could
    Lua is a great language for embedding, but one thing I wish it had was some form of optional type annotations that could be checked by a linter. Something like mypy for Lua would be super-useful. Source: almost 2 years ago

  • When type can be null or an array
    The owners of TypeScript need to do a better job at documenting language features. I always know that some sort of null/undefined handling is available but can never remember the name of the operators. And when you browse or search typescriptlang.org you cannot even find any docs on null forgiving operators. They spend more time detailing how JSX works than they do the basics of the language.
