| Not Your Father's Java (21), Not Your Mother's JavaScript |
| We are happy to announce that Dmitry Chuyko will be our special guest for this month's meeting. |
20 years ago, Java started supporting regular expressions and XML, and JavaScript learned to interact with the Document Object Model (DOM) in Internet Explorer 6 and Netscape.
Neanderthals just stopped hunting mammoths after the dot-com bubble burst, while Millennials were mastering the usage of XMLHttpRequest to send SOAP messages, which allowed users to buy philosophical compositions, including "In Da Club" and "Chihuahua."
Not to mention that WASM at that time roughly meant Open Watcom Assembler.

Currently, a new Java version is released every six months, and the ECMAScript specification is updated every year.
We designate types in TypeScript and run it on the server, and at the same time, there is a JVM implementation in WebAssembly.
We write var and anonymous functions in Java and define private fields in JavaScript classes.

| Let’s have some fun and see how many analogous things have appeared in two languages with similar names that are so often discussed as opposites. The big picture always helps to decide which instrument is better for the tail and which for the trunk. |
| JDK 21, the latest LTS release, has been out for almost a year. It's as if a Tarot card set has appeared from the fortune-teller’s sleeve. Each card has its own interpretation. These are mystical virtual streams, records that disappear when deconstructed, and collections that are now traversed backwards. It's also time to give back to the world a new "Hello World" application. The life cycle of tasks executing in different threads can be defined through structural concurrency. Some of the innovations tend to appear as features in the future, and some seek to show new wisdom, such as preparations for the ban on dynamic loading of agents. |
| Of course, divination cannot predict our future, but new features in Java are already able to improve the programs that we develop and maintain. |
