Summary of Changes

Hello @nejidevelops, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request is an automated dependency update initiated by Snyk to bring the @babel/core package and its transitive dependencies up to their latest stable versions. The primary goal is to enhance the project's security posture by patching known vulnerabilities and to incorporate the latest features, bug fixes, and performance improvements from the Babel ecosystem.

Highlights

  • Core Dependency Upgrade: I've upgraded the @babel/core package from version 7.18.2 to 7.27.4. This is a significant jump, spanning 65 minor and patch versions.
  • Security Vulnerability Fixes: This upgrade directly addresses several known security vulnerabilities, including Regular Expression Denial of Service (ReDoS), Incomplete List of Disallowed Inputs, and Prototype Pollution, as identified by Snyk.
  • Improved Performance and Spec Compliance: The new Babel versions include numerous bug fixes, enhancements for spec compliance, and various output optimizations, which should lead to more robust and potentially faster code transformations.

Code Review

This pull request upgrades @babel/core to address security vulnerabilities. A potential compatibility issue was identified due to version skew between @babel/core and @babel/preset-env. It's recommended to update all @babel/* packages to the same version.

"homepage": "https://github.com/learn-co-curriculum/js-data-structures-objects-lab#readme",
"dependencies": {
"@babel/core": "^7.4.5",
"@babel/core": "^7.27.4",

medium

It's recommended to update @babel/preset-env to ^7.27.4 to ensure compatibility with the updated @babel/core version (^7.27.4). Leaving it at ^7.4.5 could lead to unexpected behavior or build issues due to version skew.
