function bar() {
  baz();
}
 
function baz() {
  console.warn(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}
 
foo();

const Deprecation = require("deprecation");
const once = require("once");
 
const deprecateFoo = once(console.warn);
 
function foo() {
  deprecateFoo(new Deprecation("[my-lib] foo() is deprecated, use bar()"));
}
 
foo();
foo(); // logs nothing
