"and JavaScrip is an interpreted language, not a compiled one, so by default, it will be orders of magnitude slower than an app written in Swift, Rust, or C++."
This statement is misleading and false.
The distinction between "interpreted" and "compiled" isn't as clear-cut as it once was, especially in the context of modern languages and runtimes. However, when it comes to JavaScript, here's the general understanding:
-Interpreted: JavaScript is traditionally known as an interpreted language. This means that it is typically executed line by line, on-the-fly, without a preliminary compilation step to machine code. When web browsers first supported JavaScript, they essentially had interpreters that read and executed JavaScript code directly.
- Just-In-Time Compilation (JIT): Modern JavaScript engines like V8 (used in Chrome and Node.js), SpiderMonkey (used in Firefox), and Chakra (used in older versions of Microsoft Edge) use Just-In-Time (JIT) compilation to execute JavaScript code. With JIT, the JavaScript code is compiled into machine code just before it is executed, rather than being interpreted line by line. This approach can greatly improve performance because the machine code can be optimized for the current machine and can be executed much faster than interpreted code. So, in this sense, JavaScript is compiled at runtime.
- Ahead-of-Time Compilation (AOT): There are also tools and technologies that allow you to compile JavaScript (or languages that transpile to JavaScript) "ahead of time" into machine code or other languages. Examples include the asm.js subset of JavaScript and WebAssembly (although WebAssembly isn't strictly JavaScript, it's a target for languages including C/C++ and Rust, among others).
