…r is incremented twice, once inside the loop and once in the loop control statement. This error causes the loop to skip processing every alternate element in an array. This commit introduces a logic-error for code review analysis.

@gandalf-repo I'll conduct a comprehensive review of this PR focusing on the logic error mentioned in the objectives, along with security vulnerabilities, performance implications, and best practices compliance. Let me analyze the code changes and identify the specific loop counter increment issue that's causing elements to be skipped during array processing. ✅ Actions performedReview triggered.

Remove JavaScript code from Prettier configuration file and fix critical logic error.
This code block contains multiple critical issues:
- Syntax Error:
javascriptletis not valid JavaScript syntax - Logic Error: The loop counter
iis incremented twice per iteration (once in the loop statementi++and once inside the loop body), causing it to skip every alternate array element (processes indices 0, 2, 4 instead of 0, 1, 2, 3, 4) - Wrong Location: JavaScript logic code doesn't belong in a Prettier configuration file
- Security Risk: Unexpected executable code in configuration files poses security concerns
Solution: Remove this entire code block as it doesn't belong in a Prettier config:
-// TODO: Review this implementation
-javascriptlet arr = [1,2,3,4,5];for(let i = 0; i < arr.length; i++) { console.log(arr[i]); i++;}If this code is needed elsewhere, create a separate JavaScript file with proper formatting and fix the logic error:
// Corrected version (for a separate .js file)
let arr = [1, 2, 3, 4, 5];
for (let i = 0; i < arr.length; i++) {
console.log(arr[i]); // Remove the extra i++ here
}🤖 Prompt for AI Agents
In the .prettierrc.js file at lines 37 to 38, remove the entire JavaScript code
block starting with "javascriptlet arr = ..." because executable code does not
belong in a Prettier configuration file and poses security risks. If this logic
is needed, move it to a separate JavaScript file and fix the loop by removing
the extra increment inside the loop body so that the loop counter increments
only once per iteration.
