purescript/purescript
8,832Voir sur GitHubPureScript is a statically typed, purely functional programming language that compiles to JavaScript. It is designed as a cross-platform frontend language for building safe web applications, utilizing a static type system and a JavaScript compiler to ensure program correctness across browser and server environments. The language is distinguished by its emphasis on mathematical purity, featuring a robust type system with first-class support for monads. It provides a sophisticated toolset for static verification, including algebraic data types, type classes, and automatic type inference to reje
Adds boolean expressions to patterns to impose extra constraints before a specific case executes.

5,782Voir sur GitHubThis is a TC39 proposal to add declarative pattern matching syntax to the ECMAScript language. It introduces a match expression that allows developers to inspect and branch on data structures using patterns with destructuring, guards, and logical combinators. The proposal defines a custom matcher protocol via a well-known symbol, enabling objects to implement user-defined matching logic with arbitrary extraction and decomposition. The proposal supports matching against literal primitives using SameValue equality with special handling for signed zero and NaN, as well as relational comparison
Combines pattern matching with conditional guards and logical operators for precise value filtering.
