Debugging IE11 with VirtualBox

IE11 is still alive and a lot of us have to maintain support for it in our web apps. There are 2 things I never like about issues in IE:

  1. It is hard to setup an environment.
  2. The dev tools are not as friendly!

I don’t have a solution for item #2 but today I will share how I use VirtualBox to always have a setup available! It removes the friction and helps with my predisposition to fix this edge (no pun intended) cases.

Weekly Digest #6: Learning Git from novice to expert

Recently I have been helping to create content to onboard new developers. One of the topics I prepared was Git. I have been using git for more than 12 years, and while doing research I was surprised to learn new things. So I decided to share some useful links with everyone.

100 days of code was started by Alexander Kallaway in 2016 but recently it has been gaining more momentum (we all know why). Practice is the only way to master any discipline so if you have been thinking about joining the challenge, I have compiled a list of project ideas to help you get started.

Thoughts on Snapshot Testing

Since I moved to react at work I have been using and trying different testing strategies and I wanted to share some thoughts and best practices around snapshot testing.

In the past I have worked on different projects on frontend, from simple websites to complex editors. Along the journey I have used different testing frameworks and tools.

While recently snapshot testing has become popular, in my opinion it can be a double edged sword, and here is why.

Weekly Digest #1

  • Best practices on JavaScript modularity: when to use named exports, how to group code and what to avoid. Check JavaScript Module Best Practices.
  • Understanding the proxy pattern and adding that to your toolbox is super useful. In the past I have used proxies for multiple purposes (logging, performance, caching results). Learn more about JavaScript proxy in JavaScript Proxy Object Explained post.
  • Have you read “JavaScript: the good parts”? Check this article on The Magic Behind JavaScript Sintaxis Shortcuts to learn more about not so good practices (well except maybe ternary operator)
  • Planning to try all this out? Check this article on best online IDEs: 12+ Best Online Code Editors for Web Developers. I recommend Stack blitz (it is vs code online)
  • Let’s finish with some js basics. Here’s an article that quickly explains how to declare variables: JavaScript Variables: var and let and const. I tend to agree with the statements made in the article, const is your ally but there is one caveat that you need to understand. A value declared in a const cannot be mutated, but objects or arrays are always mutable constructs, so while you can declare an object or an array as a const it is possible to mutate its properties/items. It only won’t be posible to assign something else to that const!

Enjoy!!!
