Code without footguns. Ship without fear.
ClearScript eliminates the unsafety that haunts JavaScript. No automatic coercion. No hoisting chaos. No prototype pitfalls. Just a type-safe language compiled to blazing-fast WebAssembly with ten enforced laws protecting your code from entire classes of runtime bugs.
Every decision deliberately kills a JavaScript footgun.
Built from first principles to eliminate entire categories of JavaScript runtime bugs — not by adding types on top, but by redesigning the language from the ground up in Rust.
Compiled to native binaries and WebAssembly with zero garbage collection overhead. Performance that rivals C++, with the safety guarantees you can't get elsewhere.
Type system prevents automatic conversions. 5 + "3" is a compile error, not 53. Explicit is better than implicit, always. Law I enforced at compile time.
Incremental compilation with smart caching. Catch bugs instantly. IDE feedback in milliseconds. Full type checking without the 30-second TypeScript tax.
Composition over prototype chains. No more mysterious __proto__ bugs. Traits as first-class constructs give you explicit contracts and fearless refactoring.
No global namespace pollution. No mystery globals. Every symbol must be imported. Law VIII makes dependency chains auditable and refactoring safe.
Compiler errors tell you what went wrong and why. Suggested fixes. Clear error messages that teach you the language, not frustrate you. Law IX as a feature.
Not guidelines. Not best practices. Laws.
Compiler-enforced invariants that eliminate entire classes of runtime bugs. Each law is a guarantee — break one and the code does not compile. No exceptions, no escape hatches, no "trust me, this is fine."
5 + "3" is a compile error. Types must match or you must explicitly convert. The type system enforces this.
All bindings are let (immutable) or mut (mutable). Function scope is dead. Block scope only. Predictable scoping.
Code executes top to bottom. No function declarations climbing to the top. No temporal dead zones. Sequential, auditable.
Only === exists. == is banned. Comparison is always strict. 0 !== false. Every time. No surprises.
One null-like value: nil. No undefined. No NaN arithmetic. Nil is handled with explicit pattern matching or operators.
Code reuse via traits, not prototype chains. Composition over inheritance. No mysterious __proto__ bugs. Explicit.
No this binding chaos. Arrow functions and closures capture context deterministically. Refactoring is safe.
No globals. Every symbol must be imported. Dependency chains are auditable. Dead code elimination is perfect.
Compiler errors teach you. Suggested fixes. Clear messages. The compiler is your teacher, not your adversary.
One compiler, one package manager, one formatter, one linter. No ecosystem sprawl. Consistency by design.
Same intent. Radically different guarantees.
The code you want to write — without the runtime surprises. Every example below shows a real JavaScript footgun and how ClearScript's 10 Laws eliminate it at compile time.
function add(a, b) {
return a + b;
}
add(5, "3"); // "53" (coerced!)
add(5, null); // 5 (bugs)fn add(a: num, b: num) -> num {
a + b
}
add(5, "3"); // COMPILE ERROR
add(5, nil); // COMPILE ERROR
add(5, 3); // 8 ✓console.log(x); // undefined

console.log(y); // undefined

}print(x); // COMPILE ERROR

print(y); // COMPILE ERROR
let y = 10;

console.log(user.name); // Runtime error!
// Optional chaining (workaround)
console.log(user?.name ?? 'Unknown');let user = getUser(); // type: User | nil
// print(user.name); // COMPILE ERROR
match user {
User(name) => print(name),
nil => print("Unknown")
}const result = process(
transform(
filter(
data,
x => x > 5
),
x => x * 2
)
);let result = data

|> map(fn(x) => x * 2)
|> process();

10 live examples — real ClearScript syntax running in your browser. Edit any line, hit Run or press Cmd+Enter, and see the output instantly. No install. No npm. No setup.
Everywhere JS runs, ClearScript runs safer.
From browser UIs to banking backends, from CLI tools to embedded runtimes. Every domain benefits from ClearScript's type safety, explicit semantics, and zero-coercion runtime.
One binary. Full pipeline. Zero config.
From source file to WASM binary, the entire pipeline — parse, typecheck, optimise, emit — runs inside a single Rust binary. Law X is not a tagline; it is the architecture.
ClearScript source code files
Lexical + syntax analysis with strong error recovery
Bidirectional type inference with constraint solving
Intermediate representation with aggressive optimizations
WebAssembly and native binary code generation
Minimal runtime, GC-free execution
The minds behind the mission.
ClearScript is built by engineers who have shipped enterprise-scale systems and felt JavaScript's unsafety firsthand. This is not an academic project — it is the language we wished existed.

No. ClearScript is a complete reimagining of JavaScript semantics. We intentionally broke compatibility with unsafe patterns. Code that compiles to ClearScript often looks similar to JavaScript on the surface, but the ten laws eliminate entire classes of bugs. This is by design — we want a language that's safe, not one that tolerates the mistakes JavaScript does.
Not directly. However, you can write bindings to JavaScript libraries via WebAssembly interfaces. ClearScript can call out to JavaScript where necessary, but the goal is to eliminate the need — our standard library and ecosystem will provide typed alternatives to common JavaScript patterns.
TypeScript bolts types onto JavaScript but still compiles to JavaScript. ClearScript enforces the ten laws at compile time and compiles to WebAssembly, eliminating runtime coercion, hoisting, and prototype chaos entirely. TypeScript is a type system layered on top of an unsafe language. ClearScript is a safe language from the ground up.
ClearScript compiles to WebAssembly (WASM) for browsers and server-side environments, and to native binaries (x86-64, ARM64) for systems programming. You get the flexibility of multiple targets with the safety of a single language.
June 25, 2026. The compiler, standard library, and toolchain will be released under the MIT license on GitHub. We're aiming for a production-ready release with full documentation, IDE support (VS Code extension), and a growing ecosystem of libraries.
HyperBridge Digital is the company building ClearScript. Founded by KR, an architect with 15+ years of experience in distributed systems, HyperBridge has created HBForge — an 80,000-line framework with zero npm dependencies — which powers production systems and this website. ClearScript is the next evolution of that vision.
Preliminary benchmarks show 5-15× faster compile times than TypeScript, and 2-10× faster execution than JavaScript (depending on the workload). Rust-based code generation and WebAssembly compilation mean no garbage collection pauses and deterministic performance. Full benchmarks will be released at open source launch.
The community is forming now. At open source launch, we'll have contribution guidelines, a RFC process, and community channels (Discord, GitHub Discussions). We welcome compiler hackers, library authors, documentation writers, and educators. Start by reading the spec and exploring the compiler on GitHub.
Yes. For organizations adopting ClearScript at scale, HyperBridge offers consulting, training, custom tooling, and priority support. Email hello@hyperbridge.digital for enterprise inquiries.
ClearScript is the foundation for a new ecosystem where type safety, explicit semantics, and compiler-enforced laws are standard. We're building tools, libraries, and educational resources to make it easy for developers to write correct code. The vision is a world where "it compiles" means "it works."
Your next project deserves better than JavaScript.
