starlark-ts

Warning: This is an interest project aimed at learning TypeScript and compiler principles. Some parts of the code in this project are generated using ChatGPT. If you want to obtain production availability, please use starlark-go or starlark-rust.

Build and Install

# Need TypeScript and node.js environment

$ git clone https://github.com/Hanaasagi/starlark-ts
$ npm install
$ make build
$ npm run start  # Enter the REPL, or `npm run start [filepath]` to run script

The code provides an example of the syntax of Starlark:

# Define a number
number = 18

def fizz_buzz(n):
    """Print Fizz Buzz numbers from 1 to n."""
    for i in range(1, n + 1):
        s = ""
        if i % 3 == 0:
            s += "Fizz"
        if i % 5 == 0:
            s += "Buzz"
        print(s if s else i)

fizz_buzz(number)
