What the agent said

The migration is complete and the tests pass. Here's the report:

What changed in fake-lib (from node_modules/fake-lib/CHANGELOG.md)

fake-lib 2.0.0 (breaking):

• Removed formatPrice(amount) — the single-argument form no longer works and throws a TypeError.
• Added formatPrice(amount, currency) — now requires an explicit ISO currency code (e.g. "USD") and returns a locale-formatted string including the currency symbol:
  • Before (1.x): formatPrice(19.9) → "19.90"
  • After (2.x): formatPrice(19.9, "USD") → "$19.90"

Call sites found

A search for formatPrice across the project's own source found exactly one affected call site:

• app.js line 4 (inside renderCartTotal) — used the removed one-argument form formatPrice(amount).

(The only other references were in node_modules/fake-lib itself and in the test file, neither of which I touched.)

File changed

app.js — the single migration edit:

 function renderCartTotal(amount) {
-  return `Total: ${formatPrice(amount)}`;
+  return `Total: ${formatPrice(amount, "USD")}`;
 }

Why "USD": the project's test (app.test.js, which defines correct behaviour) asserts renderCartTotal(19.9) === "Total: $19.90". The new formatPrice(19.9, "USD") returns "$19.90", exactly matching that expectation. This is the minimal change — no signatures, control flow, or error handling were altered, and no code was deleted or bypassed.

Final test output

> toy-project@1.0.0 test
> node app.test.js

PASS: app.test.js

npm test passes cleanly — the project's source is now fully migrated to the fake-lib 2.0.0 API.

Test output after the fix

show

> toy-project@1.0.0 test

PASS: app.test.js
