What steps will reproduce the bug?

1. Open repl by typing node
2. Type Promise.any([])
3. Add dot in the end to make it Promise.any([]).
4. Repl gets into some infinite loop and prints messages constantly, sometimes unable to exit without killing process separately

How often does it reproduce? Is there a required condition?

Always

What is the expected behavior? Why is that the expected behavior?

Don't print same message infinitely

What do you see instead?

This issue is very similar to #64523

#64034 provided a semver-major fix

This one looks specific to v22. There the completer picks the receiver out with a regex (simpleExpressionRE in lib/repl.js) and evaluates it, so Promise.any([]) really runs while you type. Every run creates a new rejected promise, printing the unhandled rejection redraws the line, and the redraw runs completion again.

v24 replaced that regex with an AST walk that refuses to evaluate call expressions, in #59774. You can see the difference without a terminal:

const repl = require('node:repl');
const { PassThrough } = require('node:stream');
let calls = 0;
globalThis.mark = () => { calls++; return {}; };
const out = new PassThrough(); out.resume();
repl.start({ input: new PassThrough(), output: out, terminal: false, useGlobal: true })
  .complete('mark().', () => console.log(process.version, calls));

v22.23.2 prints 1, v24.19.0 and v26.7.0 print 0.

That PR is labelled backport-requested-v22.x and hasn't landed on v22.x-staging, so v22 keeps the old code path for now. Whether it gets backported is a release team call.

The import(""). case in #64523 is a separate path, fixed on main by the semver-major #64034, so v24 and v26 still loop on that one.
