    Why Nerd Lang ?

    Nerd Lang is an(other) attempt to have an efficient and yet simple language, where everything is a variable. Nerd has no superlative: it's not the fastest, it's not the best, it's not the easiest... It's Nerd.

    One of our main objective is to have a versatile tool that we can interpret, compile, or transpile. Nerd tries to have one way to do something, we will see after how to do OOP, FP or other stuffs.

    Getting started

    As this is a really alpha stage release, you need NodeJS to use NerdLang. Download and install NodeJS, and then install NerdLang with:

    npm i -g nerdlang

    You also need GCC or Clang, with support of c++17. Once done, you can start to compile Nerd files. For Arduino, you need avr-gcc in order to compile the firmware, you can get it here for Windows: To target Wasm, you need Emscripten:

    Then, you can compile your first file:

    nerd --run

    You can generate some examples in your working directory with:

    nerd --examples

    To compile and run a program, use --run

    nerd --run


    • Write the whole Nerd softwares in Nerd
    • Support Arduino, ESP32, STM32, Android, iOS, and more
    • Add all the needed standards modules
    • Add a module manager
    • Add an interpreter
    • Add runtimes in different languages
    • Language
      • support multi variable assignment
      • switch statement
      • AST optimization with native type when possible

    The Grammar / Syntax

    Nerd is close to C/C++ and JS syntax: brackets, comma, and classical expressions.

    Declare a variable

    var a = "ok";

    Assign a variable

    a = 3;

    Declare a constant

    A constant is a variable whose name starts with _:

    var _myConst = "Hello";

    Declare a function

    A function is also a variable, so you declare a function as a variable:

    var myFunction = function(_arg1, _arg2)
      // function's body 

    There is no function hoisting in Nerd, so you need to declare a function before you can use it.

    for loop

    for(var i = 0; i < 10; i++)
      // for body

    while / do while loop

      // while body
    } while(1);

    if / else if / else

    else if(2)


    var anArray = [];


    var anObject = {};
    var _aConstObject =
      property: "Hello",
      _constProperty: "World",

    Include a module

    var console = require("console");



    You can emulate classes and OOP by creating a function returning an object containing a list of function modifying an internal value:

    var _aHuman = function(_name, _age)
    	var thisScope = 
    		name: _name,
    		age: _age,
    		_pi: 3.14116, // constant property
    	var _addYear = function()
    	var _changeName = function(_name)
    	{ = _name;
    	var toReturn =
    		addYear: _addYear,
    		changeName: _changeName,
    	return toReturn;
    var _me = _aHuman("John Doe", 40);


    var _chainedFunction = function()
       var this = {};
       var then = function()
          return this;
       var end = function()
          // the end
       this.then = then;
       this.end = end;
       return this;


    npm i nerdlang
