The release of Node.js 18 brought a surprise: an experimental test runner, like other languages like Python, Go or Deno. Node.js has been around since 2009, but given that until now it has not had an official test runner, several projects have attempted to take that spot. Although the runner…

Git is probably the most popular version control system around. For many years, the git flow strategy has been the recommended way of working and system to manage and organise branches in the projects, only to be replaced by a more modern GitHub flow which is an iteration of the…

Making backups is important. You don’t want to lose all your information because of a broken device or a stolen account. One proposed solution is the 3–2–1 method (3 copies, at least in 2 different devices, and 1 of them off-site) and you should make at least one full backup…

One of the misleading use cases for beginners in JavaScript is to create constant arrays and objects. With the introductions of ES6, we got two new declarators: let, for mutable variables, and const, for constants. Many beginners believe that this will make their objects and array immutable, to discover later…

The inclusion or not of generics in the Go language has been a long-standing discussion and cause of drama since the first appearance of the language in 2009. Rivers of ink have been poured in long discussions about if generics are good or bad, and if the language needs to…

One of the most commonly noted upsides of Go is the compilation to a single binary. This makes deployments and dependency requirements easier to handle compared to other languages that require to install in the target system the individual dependencies which can potentially conflict with other software running or require…
