javascript

With Twitter being Twitter, I saw this image there, and now I can’t find it again. But it shows that the new iPhone 8 is significantly faster at rendering a cnn.com page.

Actually, since I can’t find the original source, I don’t know if they both rendered mobile web pages, or whether they tried several times to make sure it wasn’t just a hiccup. But seeing that the architecture in a little phone can come anywhere near the performance of a desktop/laptop processor that’s still being sold makes one wonder about the future.

Update: I think this was the original source of the image.

Parinfer is a tool that is currently in development, and it’s intended to help with the management of all those parentheses in languages like Lisp and Clojure. It looks like it is written in JavaScript, and intended to work with editors like Atom and Sublime Text.

In the last post about Mary Rose Cook, the reason I originally found her work again today is because she wrote a Little Lisp interpreter in JavaScript. (116 lines of code.) As shown in the image, the beginning of the article is a very quick introduction to Lisp.

This image is from a tutorial titled, Learning FP: Experiences on the Elm language.

I don’t know much about Elm yet, other than it’s an FP language for writing browser code, and it looks a lot like Haskell. As the tutorial author states, “Elm is a programming language that compiles to HTML5: HTML, CSS and JavaScript.” Another good quote is, “There are no worries about bugs due to weird mixed state as the state is always a direct result of input.”

This is a short series of quotes about learning from the book, A Smarter Way to Learn JavaScript. (With 947 reviews, that may be the most-reviewed technical book on Amazon.) It reminds me of the old quote by Sophocles that I learned in college, One learns by doing the thing.
