Breeze-nexttick is a `process.nextTick` shim that provides consistent nextTick semantics for both Node.js and browser environments. It automatically uses `process.nextTick` in Node, `postMessage` in browsers when available, or falls back to `setTimeout(fn, 0)`. This library is designed for JavaScript developers who need to write cross-platform code that requires deferred execution without changing their implementation between Node.js and browser environments.
