A few weeks ago I mentioned I was starting to learn React. I’ve finally finished a few days ago the PluralSight course mentioned in that post. The course was good for me to get my feet wet in React. However, as I stumble across React code in the Real World, I just knew I’d continue to see Spanglish in Programming.
See this example:
As I read the code above, specifically the bit indicated with red arrows, this how it sounds in my mind:
“if page type is greater than or equals to this constant and… wait, does the thing following that && actually evaluate to a boolean?!”
I have no sympathy for code that mixes different language in the same file. It gets even worse when the code mixes different languages in the same function, method, etc.
That reminds of the day XML literals were added to VB, and of course, people start using it in the worst possible ways. The ability to mix different languages can be very powerful, but to me, there should some separation so that the brain doesn’t have to deal with so much context-switching.
Anyway, the example above doesn’t look like clean code to me. I’ve asked a fellow co-worker who’s more experienced in React, and he showed me how the code above could be cleaned up: simply extract the bits that create HTML into its own functions.
I believe every developer should always ask: “Is this readable? Is this clean? Is there anyway I can make it better?”.
Much like there’s a hybrid between English and Spanish called Spanglish, there’s also one between Porguese (Português) and Spanish (Espanhol) called Portunhol. It seems like the same happens with programming languages!
Here are some cases:
- C# and T-SQL
- C# and XML
- C# and HTML
- HTML and CSS
Then I look at JSX (example found here):
So far, I’m not convinced I’ll like that approach, but hey, let me stick with it and see what kind of things I can build with this mess.
Como would usted gostar if yo tivesse written esta post the mismo jeito I escrevi this frase?
See what I’m saying? 🙂
I just got started learning React. Much like I did when I started learning Rails many years ago and documented my findings, I’ll do the same with React. If anything else, at least to have a place to come back to when I don’t remember things. 🙂
To get started, I’m following the following Pluralsight course: Building Applications with React and Flux.
Here’s a quick run through of my notes…
React has no two-way binding, which I liked in Angular. Again, I need to learn a little more about this to see how I like it.
React can render both on the client and server (different from Angular). This sounds interesting.
Instead of using Sublime to follow along the course, I decided to install Visual Studio Code on the Mac to experiment with it. So far so good.
