jsonc-parser is a Node module that scans and parses JSON that can include JavaScript-style comments (JSONC), while also working with standard JSON. It provides a fault-tolerant parser, token offsets, and helpers to visit values, build a node tree with locations, and compute/apply edits for formatting or modifying JSON documents.

Securityv4.0.0-next.1
v4.0.0-next.1 primarily upgrades a few dependencies (brace-expansion, picomatch, flatted), and includes fixes for modify() when removing the last element from an array and when removing array elements produces invalid JSON. The release notes do not mention any packaging or API shape changes.
Securityv3.3.1
Release v3.3.1 primarily updates the package version to 3.3.1. The only functional change in the diff is that the package.json "exports" map was removed.
