Programming Languages

Comparing languages

Every language has certain advantages and disadvantages. It is useful to understand these.

| JavaScript | Can run on the browser. Which means you ship to everyone on earth at once. Tightly coupled with web. For nodejs based things the advantage is a large number of libraries. There’s also good concurrency model in terms of promises. | | Java | Very very mature language. It has tons of users in the enterprise space and therefore the libraries and ecosystem around developing web services, etc are very mature |

Philosophical issues

• The issue with promises and how most languages have blue-red functions
• A response to that on why red-blue is good

Building new language, some considerations

• In this talk Herb Sutter gives the importance of value, availability, and most importantly compatibility with previous language. They give example of python2/3, javascript->typescript, etc. This was linked to from talk about Carbon which is an experimental successor to C++
