Bug Fix Request: logic error issue for code review #4
Conversation
…ly uses the equality operator (==) instead of the assignment operator (=) in a conditional statement within a loop. This results in the loop running indefinitely, causing the application to hang. This commit introduces a logic-error for code review analysis.
WalkthroughInserts non-JavaScript lines into .prettierrc.js inside the module.exports object between singleQuote and quoteProps, introducing invalid syntax that would cause parsing/loading errors. No existing configuration keys were added, removed, or renamed. Changes

37-39: Hardening: prevent accidental code insertion in configConsider:
- Switching to
.prettierrc.json(JSON can’t contain arbitrary code) if comments aren’t essential.- Or keep JS, but add a CI step that lints the config (e.g.,
eslint --no-eslintrc --parser-options ecmaVersion:2020 .prettierrc.jsor a simple static regex guard) and runsprettier --check .to fail fast on invalid configs.

🛠️ Refactor suggestion
If this snippet demonstrates the loop bug, relocate it and fix the logic
- Wrong file: Java/JS sample code does not belong inside a Prettier config.
- Typo: “javaint” should be “int” (Java) or use
let/const(JS). - Logic:
currentValue == targetValuewith 0 and 10 never executes; if the original bug was assignment in condition, in JS=would cause an infinite loop; in Java it wouldn’t compile for ints.
Move to a proper source file and correct the loop:
Java (LoopDemo.java):
public class LoopDemo {
public static void main(String[] args) {
int targetValue = 10;
int currentValue = 0;
while (currentValue < targetValue) {
currentValue += 1;
}
}
}JavaScript (examples/loop.js):
let targetValue = 10;
let currentValue = 0;
// Correct:
while (currentValue < targetValue) {
currentValue += 1;
}I can open a follow-up PR to relocate and add a small unit/integration check if helpful.

.prettierrc.js around lines 37-39 contains a stray Java/JS code snippet
("javaint...") that doesn't belong in a config, has a typo ("javaint") and a
wrong loop condition that prevents iteration or could cause a bug; remove the
snippet from .prettierrc.js, relocate it into an appropriate source file (e.g.,
src/LoopDemo.java or examples/loop.js), correct the type/keywords (use int in
Java or let/const in JS) and change the loop condition to while(currentValue <
targetValue) so the loop advances until targetValue is reached, and add a
minimal unit or integration check for the relocated example.

Critical: Non-JS code embedded in Prettier config breaks parsing and CI
The lines are not valid JavaScript and will cause Node to throw on loading .prettierrc.js, breaking Prettier and likely CI. Remove them.

Critical Fix: Remove invalid Java snippet from Prettier config
The file .prettierrc.js contains non-JavaScript code starting at line 38, causing Node to throw when loading the Prettier config and breaking CI. Remove the block below:

-If you still need a loop example, relocate it to the appropriate source file and correct the syntax:
• Java (examples/loop.java)
int targetValue = 10;
int currentValue = 0;
while (currentValue < targetValue) {
currentValue++;
}• JavaScript (src/example.js)
let targetValue = 10;
let currentValue = 0;
while (currentValue < targetValue) {
currentValue += 1;
}Optional improvement: convert to a JSON-only Prettier config (e.g. .prettierrc.json) to prevent accidental code injection and add a CI step that verifies the config parses cleanly.

In .prettierrc.js around lines 37–39 remove the invalid Java snippet
("javaint...") entirely so the file contains only valid JavaScript (or convert
the config to a JSON-only .prettierrc.json), and if you need the example move a
corrected Java example to examples/loop.java or a JS example to src/example.js;
after removing the block ensure the module.exports / export default in
.prettierrc.js remains syntactically valid and run the provided verification
command (rg -n -F 'javaint' .prettierrc.js || echo '✅ Prettier config is clean')
to confirm the bad text is gone.
