When I talk about evaluating technology for front-end development, I like to draw a distinction between two categories of technology.
On the one hand, you’ve got the raw materials of the web: HTML, CSS, and JavaScript. This is what users will ultimately interact with.
On the other hand, you’ve got all the tools and technologies that help you produce the HTML, CSS, and JavaScript: pre-processors, post-processors, transpilers, bundlers, and other build tools.
Personally, I’m much more interested and excited by the materials than I am by the tools. But I think it’s right and proper that other developers are excited by the tools. A good balance of both is probably the healthiest mix.
As someone who does some web development on the borderline of professionally and as an advanced hobbyist, this distinction is tremendously important for how and why I can afford to hang onto and practice at a reasonable level.
