StackBlitz

StackBlitz is a powerhouse, offering a full-featured development environment right in a browser, thanks to WebContainers. It's my top choice for testing large JavaScript/TypeScript code fragments or anything involving npm packages. The editor provides TypeScript types, even for installed npm packages, just like in your IDE.

CodePen

CodePen is a time-tested tool and it's pretty good for tinkering with HTML and CSS. However, I don't often use it for JavaScript because it lacks autocompletion and TypeScript type hints. While you can add external npm libraries, the absence of TypeScript IntelliSense makes it less appealing for JavaScript coding.
