reactjs-interview-questions
List of top 500 ReactJS Interview Questions & Answers....Coding exercise questions are coming soon!!
Runssource: GitHubJavaScriptMITcommit 55b7d491cd74
JavaScript, MIT licensed. The project labels itself: interview preparation, interview questions, javascript, javascript applications, javascript framework, javascript interview questions, react and react interview questions.
reactjs-interview-questions runs. An Argusic agent installed it in 7 minutes and hit 4 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.
coding-exercise builds and tests pass, coding-hooks builds, 11 of 12 coding-projects build (todo-app blocked by Windows-only dependency), star-rating project's 4 tests pass
What the agent ended up with on a clean machine, in its own words. How this is measured
Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 100 of 100 (the mean of this project's run scores).
At a glance
Subject data from GitHub, linked at the top of this page, refreshed . Test data by Argusic (CC BY 4.0); every number links to a run page with the full log, the recording, and their sha256 hashes.
What was measured
From the run that decided this verdict. Every line is a recorded value, not an estimate.
What went wrong, in the agent's own words
The agent's own words, worst first, never rewritten into advice.
- coding-hooks: vite 8 requires Node 20+, TS errors in 3 files3 minutes
- coding-exercise: default test looked for 'learn react' which doesn't exist1 minute
- theme-switcher: unused 'Provider' import with verbatimModuleSyntax1 minute
- todo-app: @rolldown/binding-win32-x64-msvc requires Windows platform
- Install time
- 7 minutes
- Cold machine to finish
- 18 minutes
- Errors hit and fixed
- 4 hit, 4 fixed with no human help
- How the result was proved
- npm test in coding-exercise passed (1 suite, 1 test); npm run test in coding-projects/star-rating passed (4 tests); npm run build succeeded for coding-hooks and 11/12 coding-projects
- Model tokens used
- 73,271
- Exact commit tested
- 55b7d491cd74
- Container image
- sha256:cdd920bce783
What was not measured
The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.
- Peak GPU memory
- this ran on a CPU machine, so there was no GPU to sample
- Behaviour over a long run
- each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
The end of the recording
The last lines of the terminal session that decided this verdict, exactly as they were recorded.
- `npm start` confirmed working **coding-hooks** (React/TS with Vite): - `npm install` succeeded with EBADENGINE warning (vite 8 requires Node 20+) - Fixed by downgrading to `vite@5` + `@vitejs/plugin-react@4` - Fixed 3 TS errors: removed unused `node:console` import in `03-useDebounceCallback`, added missin… - Build now succeeds (index.js 197 kB gzipped) **coding-projects** (13 React/TS projects): - All required vite 8 / Node 20+ — downgraded to vite@5 + plugin-react@4 - **todo-app** has `@rolldown/binding-win32-x64-msvc` (Windows-only binary) — cannot build on Linux - **theme-switcher** had TS error (unused `Provider` import) — fixed - **star-rating**: build succeeds, `npm run test` passes (4 tests) - All other 10 projects build successfully
Replay the whole session, every command from a clean machine to this point.
How it was tested
One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.
Strengths and limits
Measured facts, not opinions. How this is written.
What went well
- Reached a running state on a clean machine, with the session recorded.
- Installed in 7 minutes.
- Recovered from all 4 errors without a human stepping in, which says the failures are documented well enough to solve.
- Ran without a GPU, so it does not need one to start.
- Licensed MIT, as reported by its host.
What did not, or is not known
- Measured once so far. A single attempt shows it can run, not that it runs reliably.
What it is a reasonable choice for
- Trying it on a laptop or a small server: it reached a running state without a GPU.
- A quick evaluation: it was running 7 minutes after the clone.
Also tested, in the same area
Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

[](https://argusic.com/subject/reactjs-interview-questions)Questions
- Does reactjs-interview-questions run?
- Yes. reactjs-interview-questions runs. Argusic installed and launched it on a clean machine in 7 minutes, hitting 4 errors on the way, and recorded the session.
- How did Argusic test reactjs-interview-questions?
- On a fresh, disposable machine, with every command recorded and the repository pinned at commit 55b7d491cd74. One attempt is recorded, and the full method is on the methodology page.
- What did it cost to test reactjs-interview-questions?
- The run that produced this verdict cost $0.07: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
- How long does reactjs-interview-questions take to install?
- 7 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
- Does reactjs-interview-questions need a GPU?
- Not to start. Argusic reached a running state on a machine with no GPU.
- What goes wrong when installing reactjs-interview-questions?
- 4 things broke in the recorded run, and 4 were fixed without human help. Each one, and the time it cost, is listed on this page.
- Where is the evidence for reactjs-interview-questions?
- The recorded run is on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
