  • It was originally meant as a better JavaScript and it was. It failed when none of the other browsers expressed interest in supporting it. It languished for a while and then was taken up by the Flutter team. At the time Flutter took it up it was somewhere around the level of Java 8 in features but not quite on par. Since then it’s seen some massive improvements to the type system and language. It’s completely null sound, not just null safe like Kotlin. It recently got records/tuples and one of the more capable pattern matching syntaxes I’ve ever seen in a functional imperative hybrid language. The next stable version of dart will introduce a compiler macro system that is very promising. The syntax isn’t always the prettiest due to it trying to not totally break old code. I do think that it offers a wide range of modern language features that competes heavily with Swift and Kotlin in the mobile space.

    The facts are that large companies rarely innovate anything major. They tend to buy up smaller companies that have taken the risk and succeeded. Look at Google and Microsoft and tons of others. It’s a problem with growing big. The forces that make a company a successful scrappy little startup die out in the name of organizational efficiency. If you want to know what Apple innovated you have to look at what they did in the 70s or extend your criteria to companies they have bought.








  • It’s a highly opinionated book but it is full of good advice that in my opinion goes too far. Using a metaphor here, I think he wanted to get people to the moon but knew that he needed to give guidance to get to mars because people would look at whatever he wrote and think it’s too much.

    The book has several chapters discussing the SOLID design principles and showing how to apply them. You’ll be a better programmer for reading it. “Uncle Bob” the person can be a bit problematic so I don’t particularly like telling people to give him money. Try getting the book from the library or a second hand store. There are also videos out there of him speaking at conferences that may give a good taste of the material. He has a blog too.


  • There is a school of thought that break and continue are just goto in disguise. It helps that these two are more limited in scope than goto and can be considered less evil. If you read the book Clean Code by Robert Martin (it should be required reading for all developers), you’ll see that he doesn’t like functions to be very long. I think his rule is no more than 4 lines. I try to keep mine around 10 or less with a hard stop at 20 unless it can’t be avoided because I’m switching over a large enum or something. If you put your loops into functions then you can just use return instead of break.

    I did have a discussion with a teacher once about my use of early returns. This was when I had returned to school after many years as a professional programmer. I pointed out that my code has far less indentation than theirs and was simpler because of it and that it is common in the world outside of education. I got all of my points back he has deducted.

    You’re going to hear some good and bad advice from your teachers. Once you have a job check out what the good developers are doing and just follow them.
