This week I tweeted and tooted this question:
βWhat do you think are critical traits in a programmer? NOT to be super 10x or anything - just to feel good and function well professionally.β

I got almost a hundred replies, and wenβt through them and categorized them to see if any pattern stood out. There were suprisingly few mentions of specific technical skills, almost none at all, which made me very happy, because it shows that the industry, or at least my audience, understands that technical skillset are a symptom other habits, rather than something that arises in isolation.

# Partial script
Today Iβm going to compare templating languages, like Handlebars, to generating DOM with JavaScript, like React does. There are two main arguments for using templating languages - that they are expressive and declarative.
But there are also three big costs of using template languages, complexity, social cost, and loss of tools.
Five years ago or so, the industry standard way of rendering DOM was to use a template language to glue your business logic together with your HTML. Then a few years ago React arrived on the scene, and did away with templating languages completely, and instead just using a JavaScript in place of the templating language. The native JavaScript approach is gaining a lot of traction, but a lot of developers still hold template languages in high regard, and are not convinced that the native JavaScript approach is a step forward.
In this video, Iβm not going to talk about some cost and benefits of template languages. Some feel that templates language vs. native JavaScript is just a matter of taste - I donβt agree with that. I totally recognize that computer science isnβt physics and there isnβt a clear-cut right or wrong, but there are benefits and costs that we can and should reason about.
The two big benefits of templates are that they are expressive and declarative.
Expressive. Templating languages are very expressive, because unlike JavaScript, templating languages are designed just for expressing HTML.
Declarative. Templating languages are designed to encourage declarative interfaces. By the way, if youβre not sure what declarative programming is you can watch [this video] first and this video is going to make a lot more sense.
But, all technologies have both benefits and costs, and to add a templating language youβre paying with added complexity, social cost, and loss of tools.
Complexity. Template languages also add complexity, because they introduce an entire little language engine to your stack.
Social cost. Anyone working with your codebase now has to learn this extra little language in addition to JavaScript.
Loss of tools. If youβre using a templating language, youβre throwing away all the power of JavaScript, not just the power of the language itself, but also libraries written in it, and tooling like editors and linters.

π FUN FUN FUNCTION
Since 2015, Fun Fun Function (FFF) is one of the longest running weekly YouTube shows on programming π
thanks to its consistency and quality reaching 200,000+ developers.
π€¦ββοΈ The Failing Together concept is what makes FFF unique. Most coding content out there focus on step-by-step tutorials. We think tutorials are too far removed from what everyday development is like. Instead, FFF has created a completely new learning environment where we grow from failure, by solving problems while intensively interacting with a live audience.
