We are already in 2022/23 and I have not written anything for 2 years. You all may now (assumptions) be using Docker or K8s and by definition may have to run a bunch of commands everyday and that is a good reason you learn about writting Bash scripts even if that sounds scary to you and you do not want to, at some point you will be confronted to it, working for a new team or a new company.

Some developers may need to use different versions of Java or NodeJS on their machine and below are some hints do get it working.

Most of excel add-in developers choose ExcelDNA rather than VSTO and they are making the right decision as it performs faster relying on a C API layer.

Every day we use git and sometimes we make mistakes like deleting a branch by a single click in Sourcetree or command line instruction. If you do this, please do not panic ;)

Mixins are dead (or should be) and we could say that ES7 decorators (experimental) will provide a new way of changing object behaviours at runtime, as they give a new opportunity to modify classes or properties.

Previous blog post was about manipulating images with Javascript API and here is a recap of my notes after creating a new Chrome extension app available here.

Migration to Babel 6 was … not so easy and I just share few configuration details you may use in order to use last ES6 features.

For those wondering what is awesome Babel transpiler doing I propose to show it with an example (online transpiler can be found here for more testing).

Mozilla documentation is the best but here I share some of new es6 sugar syntaxes features you may know or not :) To my opinion it really gives a less verbose and intuitive code if we all embrace es6.

Like other languages Javascript deals pretty well with bytes and a lot of developers tend to choose NodeJS as their favourite backend framework.

This article to cover some basics you might apply in order to make a robust, readable Javascript code.

In an ideal world, to clone an object we should invoke a native method named clone() and go drink a coffee, but no, we can’t. In order to understand common manners to clone() an object in javascript, we will need to review some basics, a recap is always welcome, isn’t it ?

Before that we focus at webpack hot module replacement, let’s see some reasons why I choosed React/Webpack couple to create my blog and some extra websites:
