jQuery Market Share
Claim
"jQuery: It still runs ~75% of websites per BuiltWith"
Verification (April 2026)
| Source | Metric | Percentage |
|---|---|---|
| W3Techs | Sites with known JS library | 88.0% |
| W3Techs | All websites | 69.4% |
| HTTP Archive | Desktop pages | 75% |
| HTTP Archive | Mobile pages | 74% |
| BuiltWith | Top 1M websites | ~78% |
Verdict
The ~75% figure is slightly low. Current data shows 75-88% depending on measurement method. The claim is accurate enough but could be updated to "75-88% depending on source."
Platform absorption claim
"the platform absorbed it (querySelectorAll, fetch, classList, addEventListener)"
VERIFIED. All these native APIs now have full browser support:
- document.querySelector() / querySelectorAll()
- fetch() API
- element.classList.add/remove/toggle()
- addEventListener()
Era Boundary Claims
Claim
| E0 | 1993..2008 | human writes HTML/CSS/JS directly |
| E1 | 2008..now | framework generates HTML; human writes JS |
Verification
The 2008 boundary is questionable:
- jQuery (2006) does NOT generate HTML - it manipulates DOM
- AngularJS (2010) was first mainstream framework with HTML templating
- React (2013) crystallized the JSX-as-authoring pattern
Evidence for revised boundary
| Year | Event | HTML Generation? |
|---|---|---|
| 2006 | jQuery | No - DOM manipulation |
| 2010 | Backbone, AngularJS, Knockout | Yes - client templates |
| 2013 | React | Yes - JSX |
Recommended revision
| Era | Window | Rationale |
|---|---|---|
| E0 | 1993-2010 | Hand-written HTML/CSS/JS |
| E1 | 2010-2023 | Framework-templated (JSX, Vue, Angular) |
| E2 | 2023+ | NL/design-tool generated |
The 2008 date should be revised to 2010 (AngularJS release year).
Critical Corrections Needed
- React Hooks: Change "(2018)" to "(2019)" - released Feb 6, 2019
- Lynx ByteDance: Change "2024" to "2025" - released March 5, 2025
- Era boundary: Consider revising E0->E1 boundary from 2008 to 2010
- jQuery market share: Consider updating to "75-88% depending on source"
