What I don't like in JavaScript
a year ago
- JavaScript has a simple design, making it easy to learn.
- It features a unified variable model, allowing any type of data to be stored in variables.
- Closures are supported out of the box, facilitating complex function behaviors and encapsulation.
- Asynchronous design with async/await support enhances coding experience.
- Ergonomic syntax, comparable to Python, improves readability and writability.
- Monkey patching allows for flexible modifications to built-in functionality.
- JavaScript is performant for a dynamically typed language, sometimes rivaling C/C++.
- Versatility beyond low-level programming and backward compatibility are key strengths.
- Design flaws include type coercion quirks, though avoidable with good practices.
- `typeof null` returns 'object' due to historical reasons, causing confusion.
- Comparing two NaN values yields false, requiring special handling.
- Default `Array.prototype.sort()` sorts lexicographically, not numerically.
- Newline sensitivity can lead to unexpected behavior in return statements.
- Omitting `var`, `let`, or `const` accidentally declares global variables.
- Octal numbers with leading zeros can cause misinterpretation.
- Array constructor behavior varies unpredictably with argument count.
Show HN: Fp-filters – A curated collection of TS/JS array filter functions
a year ago

JavaScript Views, the Hard Way – A Pattern for Writing UI
a year ago
- Writing JavaScript Views the Hard Way is a pattern for creating maintainable, performant views without frameworks like React or Vue.
- Key benefits include performance (direct imperative code), zero dependencies, portability across frameworks, maintainability through strict conventions, broad browser support, easier debugging, and functional programming style.
- The approach involves structuring views with templates, DOM variables, state variables, DOM update functions, state update functions, and initialization logic.
- Templates use plain HTML with placeholders for dynamic content, avoiding interpolation for browser compatibility.
- The `init` function acts as a closure for view instances, managing DOM and state updates through clearly defined sections.
- Conventions like naming DOM nodes with 'Node' suffix and state update functions with 'set' prefix help maintain clarity and debuggability.
- State and DOM updates are separated to ensure efficient rendering and clear mutation tracking.
- The pattern supports creating reusable, framework-agnostic components with minimal overhead.
Turing-Drawings
a year ago
- Randomly generated Turing machines create images and animations on a 2D canvas.
- A JavaScript+HTML5 demo is available for trying Turing Drawings.
- Project URL: http://maximecb.github.io/Turing-Drawings/
- Patterns generated include Fractal, Scan, Matrix, Movement, and more.
- Distributed under a modified BSD license.
- Includes a blog post describing the project.
Better Error Handling
a year ago
- Bad error handling has led to significant financial losses, accidents, and operational failures.
- Error handling in TypeScript and JavaScript lacks standardization, with traditional try/catch being the most common method.
- Traditional try/catch has limitations, including lack of type safety and integration with the type system.
- Modern approaches to error handling include Go-style return tuples and monadic Result types, which treat errors as values.
- Go-style error handling is simple but can be verbose, while monadic approaches offer more features but have a steeper learning curve.
- The choice between try/catch and modern approaches depends on project complexity and team expertise.
- Community debates highlight tradeoffs between performance, developer experience, and error handling strategies.
- Practical implementation strategies suggest catching and wrapping errors from external libraries early.
- The article concludes with a preference for Rust-style error handling but acknowledges the suitability of different approaches based on context.
