ES6 features and specs

  • Arrow Functions
    Enable a more concise syntax for writing function expressions, and automatically bind the context, which simplifies working with 'this'.
  • Template Literals
    Allow embedding expressions and using multi-line strings, improving string manipulation and readability.
  • Destructuring Assignment
    Provides a clear and concise way to extract values from arrays and objects, leading to cleaner and more readable code.
  • Classes
    Bring a more familiar object-oriented approach to JavaScript, offering syntactic sugar over JavaScript's prototype-based inheritance.
  • Modules
    Facilitate code organization by allowing the import and export of modules, enabling better modularity and reusability.
  • Promises
    Introduce a simpler way to deal with asynchronous operations, making it easier to handle errors and work with callbacks.
  • let and const
    Introduce block-level scoping to variables, reducing the likelihood of bugs associated with hoisting and variable scope issues.

Possible disadvantages of ES6

  • Compatibility Issues
    Some environments, especially older browsers, may not fully support ES6, requiring transpilation to ES5 with tools like Babel.
  • Learning Curve
    Developers familiar with ES5 may need time to adapt to new syntax and features, potentially slowing down immediate productivity.
  • Babel Required for Older Browsers
    To ensure browser compatibility, projects often require Babel or similar tools to transpile ES6 code to ES5, adding complexity to the build process.
  • Complexity in Tooling
    ES6 introduces new tools and build systems like Webpack, which can be complex to configure for beginners.

D (Programming Language) features and specs

  • Performance
    D is designed to be a high-performance systems programming language, offering performance comparable to C and C++ through native machine code compilation.
  • Expressiveness
    D features a rich standard library and modern language constructs, such as garbage collection, first-class arrays, and advanced templating, making it easier to write expressive and maintainable code.
  • Memory Safety
    D offers optional garbage collection along with manual memory management. This hybrid approach can help in developing safer applications by reducing memory-related errors.
  • Interoperability
    D can easily interoperate with C API, enabling seamless integration with existing C libraries and systems. It also supports better C++ interoperability compared to other languages.
  • Built-in Unit Testing
    D has built-in support for unit tests, allowing developers to write and run tests as part of the language itself, facilitating test-driven development.
  • Concurrency
    D offers built-in concurrency support with message passing, similar to the actor model found in languages like Erlang, making it easier to write concurrent and parallel programs.

Possible disadvantages of D (Programming Language)

  • Adoption
    D is not as widely adopted as other languages like C, C++, or Java. This limited adoption means fewer libraries, frameworks, and community support.
  • Toolchain Maturity
    While D's compilers and tools have improved over the years, they may still lack the maturity and feature set of more established languages, which can affect developer productivity.
  • Learning Curve
    D's richness and combination of paradigms (such as imperative, object-oriented, and functional programming) can present a steep learning curve for new developers.
  • Garbage Collection
    Although D offers optional garbage collection, its reliance on it for memory safety might be seen as a drawback for real-time system development where deterministic memory management is crucial.
  • Ecosystem
    The ecosystem for D is less vibrant compared to more popular languages, leading to potentially fewer third-party libraries, tools, and resources.
  • Standard Library Documentation
    The standard library documentation can be inconsistent or less comprehensive compared to other languages, making it difficult for developers to fully utilize all features of the language.

Analysis of D (Programming Language)

Overall verdict

  • Overall, D is a solid programming language choice that balances performance with productivity. It may not be as widely adopted as some other languages, but it has a dedicated community and continues to evolve, making it a viable option for various programming tasks.

Why this product is good

  • The D programming language is considered good by many developers for various reasons. It combines the performance and low-level control of C/C++ with the expressive power and ease of use found in modern languages. D offers features like garbage collection, first-class functions, and compile-time function execution, providing both speed and flexibility. Its interoperability with C, the convenience of a powerful standard library (Phobos), and the availability of packages via the DUB package manager make it a practical choice for systems programming, application development, and rapid prototyping.

Recommended for

  • System programming enthusiasts looking for an alternative to C/C++
  • Developers interested in writing high-performance applications
  • Programmers who appreciate modern language features and strong community support
  • Projects requiring seamless C integration
  • Individuals looking for a language that supports easy code maintenance and scalability

ES6 mentions (17)

  • A comprehensive guide to JavaScript generators
    Generators were first introduced in ES6 and have since become a fundamental part of the language. They are defined using the function keyword suffixed with an asterisk like: function*. Hereโ€™s an example:. - Source: dev.to / 8 months ago
  • Common JavaScript Mistakes Developers Make
    Block scope: Introduced in ES6 (ECMAScript 2015), block scope allows you to declare variables with the let and const keywords within specific code blocks defined by curly braces, such as if statements, loops, and arrow functions. This provides even more precise control over variable accessibility and helps prevent unwanted side effects. - Source: dev.to / about 1 year ago
  • You're parsing URLs wrong.
    But JavaScript didn't always have a good way to construct and parse URLs built in. The URL object was first included in the ECMAScript 2015 specs. - Source: dev.to / over 1 year ago
  • Time, Space and Complexity
    The ECMAScript 2015 (ES6) standard introduced the concept of "proper tail calls" (PTC), which mandates that compliant JavaScript engines must implement TCO for tail calls. PTC ensures that a function call in tail position does not increase the call stack size, thus allowing for potentially infinite recursive calls in constant stack space. - Source: dev.to / almost 2 years ago
  • Var, Let , Const - Javascript basics
    Let was introduced in ES6ECMAScript2015. It is Block Scoped, any code written within {} is said to be in a Block. So, that's the restriction that ECMA wanted to implement with let, making variables inaccessible outside the block. - Source: dev.to / over 1 year ago
