> Real Static Typed Script - RSTS project.

StaticScript is a language on top of TypeScript as frontend and LLVM as backend for code-generation to binary.

### How it was implemented

My talk about How it's working on hight level and about V8/JIT and etc

I prepared two talks on PiterJS meetup with explanation about how it was implemented

***Part 1***

# Installing

For latest stable version:

```sh

npm install -g static-script

```

# Let's write simple example

Put it in `calculate-pi.ts`

```ts

{

    function calculatePI(cycles: number): number {

        let inside = 0;

        for (let i = 0; i < cycles; i++) {

            let x = Math.random() * 2 - 1;

            let y = Math.random() * 2 - 1;

            if ((x*x + y*y) < 1) {

                inside++

            }

        }

        return 4.0 * inside / cycles;

    }

    console_log(calculatePI(1000000000));

}

```

Next compile it:

```sh

$ ./bin/ssc calculate-pi.ts

```

Next run it:

```sh

$ time ./output/main

```

This will produce:

```

./output/main  0,01s user 0,00s system 80% cpu 0,013 total

```
