Results:
npm warn deprecated glob@7.2.3: Glob versions prior to v9 are no longer supported
npm warn deprecated glob@7.1.4: Glob versions prior to v9 are no longer supported
npm warn deprecated glob@7.1.4: Glob versions prior to v9 are no longer supported
added 40 packages, removed 317 packages, changed 348 packages, and audited 1763 packages in 4m
