Check Documentation in JavaScript

Hover over a symbol or use a shortcut to quickly review documentation.

Need to quickly check docs for the standard JavaScript methods and other symbols but don’t feel like googling? Hover over a symbol or press F1 (macOS) / Ctrl+Q (Windows/Linux) to invoke the Documentation popup. If needed, you can also go to the corresponding MDN page for more details right from there (make sure to press F1 (macOS) / F1 (Windows/Linux) to see the MDN link).
