# -Egg-programming-language-with-javascript In this section, I created a simple JavaScript-based programming language. I wrote this to gain a deeper understanding of how programming languages work, and it was very instructive for me. # Prerequisties * install node js # installation Check that the node is installed on your system otherwise install it through [install-node-js](https://nodejs.org/en/) second download or clone this project via terminal command: ```shell git clone https://github.com/Miladxsar23/Egg-programming-language.git ``` # Syntax Like all programming languages, our language follows a certain syntax to perform certain operations. Syntax | arguments | Description --- | --- | --- | if | (condition, trueCallbak, falseCallback) | The if statement works by checking that if the first argument is true, it calls the second argument, otherwise it calls the third argument.| while | (condition, callback) | The while statement works by calling the second argument until the condition is met in the first argument | do | (task1, task2, ...) | Uses this expression to sequence mattresses | define | (variableName, variableValue) | To define variables, we use the expression that the first argument is defined as the name of the variable and the second argument as the value of that variable. | fun | (arg1, arg2, ..., body) | We use it to define a function. The last argument is interpreted as the body of the function and the rest of the arguments are interpreted as function arguments. | set | (variableName, variableValue) | Used to change the value of a predefined variable | # Enviroinment variable Like all languages, our language has a set of internal values called environmental variables, which are interpreted based on their values. name | arguments | Description --- | --- | --- | array | (value1, value2, ...) | Defines an array | length | (string || array) | return a length of array or string | element | (array, index) | return a value at index in array | print | (arg) | print a arg in console | false | --- | false (boolean value) true | --- | true (boolean value) \* | --- | multiplication operation \+ | --- | sum operation \- | --- | mines operation \/ | --- | division operation \> | --- | Comparative operation \< | --- | Comparative operation \== | --- | Comparative operation ## Comment in egg language To write a comment, just use the # sign at the beginning of your sentence, then the whole line will be considered as a comment. ``` # this is a comment define(count, 1) ``` # How run *egg* program??? First create a file with the .egg extension and then write your egg program in it : *test.egg* ``` do(define(total, 0), define(count, 1), while(<(count, 11), do(define(total, +(total, count)), define(count, +(count, 1)))), print(total)) # ouput is 55 ``` In the next step, just run its interpreter, Egg.js, with node and send your program file as input to it : ***Be sure to open your terminal along the root of this project*** ```shell node src/code/Egg.js //example node src.cide/egg.js test.egg ``` ## Contributing As I use this for my own projects, I know this might not be the perfect approach for all the projects out there. If you have any ideas, just [open an issue](https://github.com/Miladxsar23/Egg-programming-language/issues/new) and tell me what you think. If you'd like to contribute, please fork the repository and make changes as you'd like.
