Compare the same interactions.
TodoMVC behavior and measured add, complete and delete interactions for 100 items.
TodoMVC behavior
Editing (double click, Enter, blur, Escape and empty deletion), bulk completion, clearing completed items, URL filters, counters and persistence were regression-checked in Chromium.
Uses official styles and the standard screen. This does not claim official acceptance or all-browser certification.
Time for 100-item interactions
Median synchronous duration; lower is faster. Includes UI and storage work, excludes startup and network waits. Nine alternating-order measurements after two warmups.
| Interaction | Mithril / Jev + UI | Vanilla ES6 reference |
|---|
Complete and delete operations took longer than the reference. These measure browser execution of Jev-assembled logic, not coding-model ability or generation speed.
Speedometer 3.1 reference
Ten iterations of the unmodified official suite. Mithril is excluded from this score. This exploratory automated measurement on development Chromium and a working Mac does not establish stable-browser rankings.
Conditions and records
The UI was implemented by the host. Jev records cover toggle and remaining-count assembly; the new UI was not all generated by Jev.
