language_name is a small embeddable scripting language
language_name is inspired by Javascript, Lox, Lua, Python, Rust and more
# Reference
## Overview
Declaring variables using `let`
```
let hello = 4;
```
Semicolons are needed :)
```
let test = 5;
let another = 4;
```
The language has strings, numbers, arrays, objects and null and booleans
```
let string = "hallo";
let number = 4;
let array = [];
let object = {};
let _null = null;
let bool = true;
```
You access properties on objects using `.`
```
let obj = {};
obj.hi = "hi!";
```
Functions are first class
```
let obj = {};
obj.hello = helloFn;
obj.hello();
```
Functions are declared using `fn`
```
fn greet(name) {
return "hello, " + name;
}
```
Comments using `#`
```
# hi!
```
Multiline comments using `##` until `##`
```
##
hi
comment
##
```
There are many native functions, that can easily be customized and added/removed by the host
```
# rocket game
turnRocketLeft(29);
turnRocketRight(32);
# chat bot
message.respond("hi");
# dangerous http requests
fn callback(html) {
print(html);
}
fetch("https://github.com/Nilstrieb", callback);
```
Basic arithmetic and boolean logic is available
```
let a = 5;
let b = 5;
print(a + b / b * b - a % b);
print(true and false or false or true and false);
```
Loops and conditionals
```
let x = true
if x {
print("true!");
} else {
print("false :(");
}
loop {
while 1 > 5 {
print("yeet");
break;
}
# no for loops for now, but will be added (probably like python)
}
```
_ is dynamically and *strongly* typed
