About Coding Dunia
Coding Dunia publishes practical, in-depth guides on React, TypeScript, JavaScript, and modern frontend development. Every article comes from real production experience, no filler, no sponsored content, no affiliate-stuffed comparison pieces that exist only for the link revenue.
The goal is simple: explain complex frontend topics the way an experienced engineer would explain them to a colleague, not the way a textbook would. If a tip didn't survive contact with a real codebase, it doesn't make the article.
Editorial Policy
We don't accept sponsored articles. We don't take payment to recommend a library, tool, or framework. When a guide mentions a paid product (a hosted CI provider, a managed database, an editor), it's because we use it on our own projects, not because the vendor reached out. The same applies to comparison posts: ranking comes from hands-on testing, not vendor decks.
When we link to an external library or service, it's a plain link, no affiliate redirects, no UTM tags appended for tracking, no rel="sponsored" that we forgot to disclose. If we test paid tooling, the article says so explicitly and explains how we got access (free tier, trial, or paid out of pocket).
Errors get fixed publicly. If a reader catches something wrong, a deprecated API, a benchmark that no longer holds, a TypeScript version that changed behavior, we update the article and note the change at the top. Old guides aren't deleted; they're updated or marked outdated with a link to the current version.
How We Test and Update Content
Every code example runs. Before publication, snippets in TypeScript, React, and Node.js guides are executed against the versions stated in the article, and the versions are re-tested whenever a major release lands. Benchmarks are measured on hardware described in the article (typically an M-series MacBook Pro and a Linux CI runner) rather than copied from vendor marketing.
Time-sensitive guides (anything tied to specific library versions, framework releases, or year-dated comparisons) get a freshness review every quarter. The "Last updated" date on each post reflects the most recent factual review, not just a republish for SEO purposes.
