​​I’ve been programming computers since the 1980s. In that time, I’ve seen and used a lot of languages and technologies that have come and gone. I watched as the web blossomed with new features, like browsers exchanging XML data asynchronously.

Most of the time, this data is exchanged as JSON, or YAML, HTML or some other format.

What we often overlook in these debates is that every programming language and platform is criticized based on certain issues, which are created by how we use the platform.

​​​​A few months ago, I wrote an article based on optimizing React loading time, and most of the readers’ comments suggested trying Preact to get default optimization. So I decided to try Preact with the same app used for the previous article. Let’s first get an intro about Preact.
