Research direction

Start with 1-js/02-first-steps/05-types/article.md at the linked typeof section and compare its alert example with a browser console and a Node.js or terminal runtime. Done means the text clearly identifies the browser-only context and shows the corresponding undefined result outside the browser.

Written by the indexing model from the issue text.

Description

The current page mentions:

typeof alert // "function"

But in Node.js / VS Code / terminal / online JS runners → alert does NOT exist. So it's gives undefined.

typeof alert // "undefined"

It should mention about the about the Browser Console

typeof alert // "function" (Browser Console)
