Not altJS. [Play online ▶](https://aiscript-dev.github.io/aiscript/) AiScript is a multi-paradigm programming language that runs on JavaScript, not AltJS (1). * First-class support for arrays, objects, functions, etc. * Flexibility, including conditional branches and blocks can be treated as expressions * Easy to write, no need for semicolons or commas * Runs in a secure(2) sandbox environment * Variables and functions can be provided from the host > (1) ... It "runs on" JavaScript, not is "converted" to JavaScript. Therefore, it is not AltJS. > (2) ... Not being able to access the host's information. This repository contains parsers and processors implemented in JavaScript. Note: AiScript and [Misskey](https://github.com/syuilo/misskey) are completely independent projects. AiScript does not prescribe any specific host, but Misskey is the largest user of AiScript (today!) ## Getting started (language) [See here](https://aiscript-dev.github.io/en/guides/get-started.html) ## Getting started (host implementation) [See here](https://aiscript-dev.github.io/en/guides/implementation.html) ## Example programs ### Hello world ``` <: "Hello, world!" ``` ### Fizz Buzz ``` for (#i, 100) { <: if (i % 15 == 0) "FizzBuzz" elif (i % 3 == 0) "Fizz" elif (i % 5 == 0) "Buzz" else i } ``` ## License [MIT](LICENSE)
