FunctionalScript

FunctionalScript is a safe, 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.

A working draft of the FunctionalScript specification.

Vision

We aim to create a safe, cross-platform programming language that can work in any JS platform without any build step. There are thousands of programming languages, and we don't want to create another one that others must learn. Instead, we take the opposite approach: we remove everything that makes the most popular and cross-platform language unsafe, insecure, or less portable.

Applications

FunctionalScript code can be used:

safely in any JavaScript/TypeScript application or library;
as a JSON with expressions, see DJS;
as a query language,
as a smart contract programming language in DeFi.

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.

Our Next Step

Re-architecture of NaNVM.
