# TypeScript Compiler
A TypeScript compiler for the monkey programming language, based on the excellent book ["Writing An Compiler In Go"](https://compilerbook.com/)
## ⚙️ Installation
To get started, clone the repository:
```bash
git clone https://github.com/bpetermann/ts-compiler.git
cd ts-compiler
```
Then, install dependencies and build the project:
```js
npm run build:fresh // Installs dependencies and builds the project
```
## 🚀 Start
Finally, start the REPL (Read-Eval-Print Loop):
```js
npm run start // Starts the REPL
```
## 📋 Usage Examples
```js
>> let a = 2; // Declare a variable
>> let baz = ["foo", "bar"]; // Declare an array
>> baz[0]; // Acesss array
>> let person = {"name": "Alice"}; // Declare a hash map
>> person["name"]; // Access map
```
Here's a basic example illustrating the declaration and invocation of a function:
```js
let fibonacci = fn(x) {
if (x == 0) {
0
} else {
if (x == 1) {
return 1;
} else {
fibonacci(x - 1) + fibonacci(x - 2);
}
}
};
fibonacci(5);
```
Example of closures:
```js
let newClosure = fn(a) {
fn() { a; };
};
let closure = newClosure(99);
closure();
```
Close the REPL:
```js
eof;
```
## Syntax Overview
The syntax embodies a rich spectrum of functionalities, managing mathematical expressions, variable assignments, function definitions, calls, conditionals, and returns. It adeptly handles concepts like higher-order functions and closures.
Additionally, the compiler accommodates diverse data types — integers, booleans, strings, arrays, and hashes.
It also features a set of built-in functions tailored to expedite string/array operations and console output logging.
## 🧪 Tests
The following command will run all jest test suites:
```js
npm run test
```
