Skip the garbage collector.
W uses no garbage collector or conventional heap. It reuses temporary storage and constructs results directly in their destinations.
W / A GENERAL-PURPOSE LANGUAGE
Write clearly.
Go deeper.
A heapless language targeting WebAssembly, with familiar syntax, explicit types, and control over memory.

01 / THE APPROACH
Less runtime overhead.
More room for your code.
Useful building blocks with low-level control when your work calls for it.
Reduce unnecessary work.
W is designed to eliminate intermediate objects, fuse operations, and specialize hot paths. Less time moving data that does not need to exist.
Keep control when it matters.
Explicit numeric types, pointers, fixed arrays, and typed memory operations are part of the design, alongside SIMD and atomics.
02 / THE SYNTAX
Familiar structure.
Clear intent.
The function adds the integers from zero up to, but not including, limit. For example, sum(10) returns 45.
- pub fn
- Declares an exported function.
- mut
- Allows a local value to change.
- rt
- Returns the result.
sum.w
pub fn sum(limit: i32): i32 {
mut total: i32 = 0
mut index: i32 = 0
while index < limit {
total += index
index += 1
}
rt total
}PROJECT STATUS
In active development.
W is currently private. Syntax and supported features may change as the language develops.
