What the React measure says
React appeared in 124 of 428 observed opportunities (29%) in the dated 2026-W42 edition. Each opportunity contributes at most one count to the React bucket, even when the same label appears multiple times in its normalized technology fields.
| Measure | Published value | Denominator / rule |
|---|---|---|
| Observed opportunity count | 124 | n=428 observed opportunities |
| Incidence in sample | 29% | Multi-label categories may overlap |
| Technology classification coverage | 426 / 428 (99.5%) | Edition-wide QA context |
Engagement context for the whole edition
The source snapshot does not publish technology-by-engagement cross-tabs. These rows describe all 428 observed opportunities and must not be quoted as React-specific buyer intent.
| Stated preference | Opportunities | Share |
|---|---|---|
| Solo developer | 15 | 3.5% |
| Company or agency | 7 | 1.6% |
| Solo or company | <5 | Withheld |
| Not stated | 406 | 94.9% |
Budget context for the whole edition
125 of 428 opportunities had a publishable comparable amount (29.2%). Currency and unit groups stay separate; fixed totals are not a market-size estimate.
| Group | Comparable / raw n | Comparable median | Comparable middle 50% | Comparable fixed midpoint | Raw fixed midpoint | QA |
|---|---|---|---|---|---|---|
| USD · Fixed | 115 / 116 | $500 | $100 — $1,500 | $197,222 | $1,197,222 | Review · 1 excluded |
| GBP · Fixed | 6 / 6 | £565,804 | £107,902 — £1,000,000 | £3,734,234 | £3,734,234 | Not flagged |
The dominant-upper-tail review is evaluated on observation-level amounts. Flagged values remain in the raw aggregate but are excluded from comparable medians, ranges and fixed totals. “Not evaluable” means this frozen fallback predates observation-level outlier metadata; it is not a clean result.
Bounded interpretation
The defensible statement is narrow: within the dated 2026-W42 sample, Leadiy classified React in the published count shown above. The page cannot establish direction of change because this edition has no historical baseline. It also cannot establish exclusive technology choice because one opportunity can count toward several technologies.
What this page cannot answer
- Technology categories are multi-label and may overlap; this is incidence, not market share.
- The dataset does not publish technology-specific organization, engagement, budget, salary, duration, seniority, geography, or co-occurrence figures.
- Edition-wide engagement and budget tables are context for the same sample, not filters for this technology.
- A dated edition is a snapshot of observed sources, not a historical trend or forecast.
- Aggregate outlier review is a QA flag, not a finding that an underlying opportunity is incorrect.
