```ts

import LLVM from "./llvm";

function main() {

	// initialize LLVM

	const ctx = new LLVM.Context();

	const mod = new LLVM.Module("demo", ctx);

	const builder = new LLVM.IRBuilder(ctx);

	// define types

	const i32 = LLVM.Type.int32(ctx);

	const fnType = new LLVM.FunctionType([i32, i32], i32);

	// {} are used to separate scopes (optional)

	{

		// create the function

		const fn = mod.createFunction("add", fnType, { linkage: LLVM.Linkage.External });

		const entry = fn.addBlock("entry");

		builder.insertInto(entry);

		

		{

			// get parameters & add them

			const [a, b] = fn.getArgs();

			const sum = builder.add(a, b);

			

			// return the result

			builder.ret(sum);

		}

		// make sure the function is valid

		fn.verify();

	}

	

	// verify the module

	mod.verify();

	

	// output IR

	console.log(mod.toString());
