Javascript
I use Javascript everyday. I think it's a great language for letting ones own programmer creativity run loose due its accessibility and how mutable everything is.
Typescript
I like using the Typescript compiler and linter. They are very effective at making sure we do not input the wrong type. In Javascript, the most common thing is a value being undefined when it shouldn't be and the whole program crashes.
Node
Node is what I reach for anytime I need to quickly manipulate a filesystem. I think any Javascript developer will eventually start to feel limited by the browser and will need to venture to Node.
Git
I embraced Git from the start and I have experience working with others on Github and Gitlab. I can't imagine being a programmer without Git. I've been saved many times from it. I use it for nearly all my probjects.
HTML
I learned HTML when I was just a kid. I would make very basic web pages. So when I began my programming journey, it was something I didn't have to work too hard for. I know enough HTML for my needs and any more is just a quick google away.
Sass
Sass is one of those technologies I love. I find Sass very intuitive and I always use Sass and not scss. I appreciate the cleanliness and ease of readability. Also the indent notation is sweet.
VIM
I really love VIM and I use it exclusively. Key skills include: opening and closing VIM. Just kidding! It improves my workflow and I have fun hopping around the code. I also like the feeling of continuously improving at it.
Shell
The shell is the shell. None of us programmers want to waste our time mouse clicking through file systems.
Ruby
I have a little experience with Ruby. I can write basic functions and conditionals and use many of the built in methods. Middleman and haml are for Ruby and I have good experience working with them.
Middleman
Middleman is a static website generator. It allows me to write helper methods, use partials, generate proxy pages, and a myriad of other things. It's based on ruby. I used Middleman for this portfolio.
HAML
HAML is very nice for writing clean html. I prefer to use it any time I can. It's good for writing inline Ruby code in Middleman and it saves a bunch of time!
Unpoly
Unpoly is a Javascript framework. I use it for smoother navigation. It's also quite useful for automating simple Javascript elements, like a hamburger menu or pop up.
BEM
Block Element Modifier. The theory behind it makes a lot of sense, and it does keep things more ordered. BEM helps mitigate a lot of the the tendancy of css to get chaotic. I mostly only use BEM on larger projects.
Leaflet
Leaflet is great when you want to style and plot a map. The documentation is very accessible and everything is just a search away.
