Related: [Run bash code](/docs/code-interpreting/supported-languages/bash.md), [Run Java code](/docs/code-interpreting/supported-languages/java.md), [Run Python code](/docs/code-interpreting/supported-languages/python.md), [Run R code](/docs/code-interpreting/supported-languages/r.md)

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>The E2B Code Interpreter supports TypeScript, top-level await, ESM-style imports and automatic promises resolution.</Note>

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

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

// Install the axios package

// Run the code
