Recipe: Once Function

Category: Performance

Problem

You need a quick, reliable snippet for once function in a real project.

Solution 

  // Once Function
export function recipe(input) {
  if (input == null) return null;
  // Core logic here — adapt to your codebase
  return { ok: true, value: input, recipe: "Once Function" };
}

Usage 

  import { recipe } from "./once-function.js";
console.log(recipe("example"));

Notes

  • Adjust naming and error handling to match your style guide
  • Prefer built-in APIs when available
  • Add tests if this ships to production
