ezc

A stack-based programming language with arbitrary-precision integers, 16 numeric types, and first-class editor tooling. Code is a flat sequence of values and operators in reverse Polish notation.

# sum of squares from 1 to 10
10 iota (sq) map sum

No ceremony. No types to declare. Just push values, apply operators.

Why ezc?

• Big integers by default — int is arbitrary-precision. Fixed-width types (u8–u256, i8–i256, f16–f64) are opt-in.
• Mathematical focus — clean operator algebra, type-family promotion, no surprises with overflow.
• First-class tooling — debugger (DAP), language server (LSP), and extensions for VS Code, Neovim, Zed, and Helix.
• Runs in the browser — every code block on this site is runnable.
