FunctionalScript

FunctionalScript is a purely functional programming language and a strict subset of ECMAScript/JavaScript. It's inspired by

• JSON and JSON5 as subsets of JavaScript. JSON is also a subset of FunctionalScript.
• asm.JS/WebAssembly, as a subset of JavaScript.
• TypeScript, as a superset of JavaScript.

Design Principles

In FunctionalScript:

• Any module is a valid JavaScript module. No additional build steps are required.
• Code should not have side-effects. Any JavaScript statement, expression, or function that has a side effect is not allowed in FunctionalScript. There are no exceptions to this rule, such as unsafe code, which can be found in Rust, C#, and other languages.
• A module can depend only on another FunctionalScript module.
• It also has no standard library. Only a safe subset of standard JavaScript API can be used without referencing other modules.

Applications

FunctionalScript code can be used:

• in any JavaScript/TypeScript application,
• as a JSON with expressions,
• as a query language.
