Can you write an OS in PHP?

And yes it’s possible to create an operating system using interpreted languages.

Does PHP compile to JavaScript?

It starts by tokenizing the PHP code into tokens, which it then uses to build an AST tree. Once the tree has been constructed, the script compiles it into JavaScript that can be interpreted by the VM and then executes it.

Is C++ better than node JS?

C++ uses the CPU and performs up to 10X faster than Node. js doing mathematical operations.

Is C++ faster than JavaScript?

C++ is ten or more times faster than JavaScript across the board. There is no argument which is faster. In fact, a lot of the time when you compare two languages it’s going to be the C language with faster compile time. This result is because C++ is mid-level and compiled.

Can JavaScript call C++?

js 8 offers new API for C++ Addons called N-API. The resulting glue code that allows calling the C++ functions from JavaScript is located in src/node. cpp . N-API and node-addon-api are well-documented, so I won’t go into details here.

Is there any tool that can generate JS code with C?

Almost always this tool exists. It proofs that JS codebase maybe the biggest codebase ever. JS code can be generated with Java, Python, and other languages. Interesting idea: The Reason language is based on the OCaml’s backend and was developed to generate JS. OCaml bytecode can be translated into C code.

Is it possible to execute JavaScript-function in PHP?

If I understand you right, you’d like to execute a JavaScript-function in PHP JavaScript is executed in the browser (client side), PHP is server-sided, so unless you write a JavaScript-parser in PHP, that won’t work.

Can JavaScript be written in C/C++?

All the answers so far are correct, but since it hasn’t been mentioned yet, JavaScript can be written in JavaScript. Most Javascript interpreters are written in C/C++ (V8, Nitro, etc…), however a compliant interpreter can be written in any language (Rhino→Java, Interpreter→Javascript, etc…).

Is there a way to compile JS code into native code?

It means that Reason (maybe) allows you to write both WebAssembly and JS. Another approach is to compile JS into LLVM bytecode. Theoretically, that can provide JS compilation into native code and WebAssembly.
