JavaScript: Global Functions Without Property Key "prototype"

Here is code to print all global function objects and report if they have key "prototype" .

// print all global function objects and report if they have key "prototype"

const x_yes = [];
const x_no = [];

(Reflect.ownKeys(globalThis)).forEach(
  (x) => {
    if (typeof globalThis[x] === "function") {
      if (globalThis[x].hasOwnProperty("prototype")) {
        x_yes.push(x);
      } else x_no.push(x);
    }
  },
);

console.log("Has key prototype", x_yes);
