jQuery versus You Might Not Need jQuery
Compare	jQuery	You Might Not Need jQuery
Verdict	Depends	Worth it
Best for	Legacy sites already built on jQuery	Developers dropping jQuery from new sites
Who it's not for	New greenfield apps . use native JS or a framework	Teams supporting IE-era browsers . jQuery still earns its keep
Privacy	Mature library with a real CVE history; risk concentrates in old 3.x versions and unmaintained plugins.	No known public vulnerabilities found in the sources reviewed.¹²
Support quality	Community-driven; paid LTS via HeroDevs/TuxCare	Community resource, no support
Public sentiment	Developer consensus: jQuery is everywhere and easy, but most now treat it as a legacy-maintenance tool, not a choice for new projects.^³	Developers treat it as the canonical nudge toward vanilla JS, while most agree 'might' is the operative word.
Biggest gotcha	Stuck on 3.x? Critical fixes only; ongoing security patching means paying HeroDevs or TuxCare.^⁹	Browser-support caveats . 'That's not always safe'; test snippets before shipping¹⁴
