# Run JavaScript code
Use the `runCode`/`run_code` method to run JavaScript code inside the sandbox.

# Run JavaScript and TypeScript code

Use the `runCode`/`run_code` method to run JavaScript and TypeScript code inside the sandbox.
You'll need to pass the `language` parameter with value `javascript` or `js` for JavaScript and `typescript` or `ts` for TypeScript.

<Note>
Our code interpreter has been updated to enable support for TypeScript, top-level await, ESM-style imports and automatic promises resolution.

```js
import { Sandbox } from '@e2b/code-interpreter'
import { Sandbox } from "@e2b/code-interpreter";

// Create a new sandbox
const sbx = await Sandbox.create();

// Install the axios package
await sbx.commands.run("npm install axios");

// Run the code
const execution = await sbx.runCode(`
import axios from "axios";

const url: string = "https://api.github.com/status";
const response = await axios.get(url);
response.data;
`,
{ language: "ts" }
);

const sbx = await Sandbox.create()
const execution = await sbx.runCode('console.log("Hello, world!")', { language: 'js' })
console.log(execution)
console.log(execution);
