console: dir() static method
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
Note: This feature is available in Web Workers.
The console.dir() static method displays a list of the properties of the specified JavaScript object. In browser consoles, the output is presented as a hierarchical listing with disclosure triangles that let you see the contents of child objects.
Unlike other logging methods, console.dir() does not attempt to pretty-print the object. For example, if you pass a DOM element to console.dir(), it will not be displayed like in the element inspector, but will instead show a list of properties.
In runtimes like Node and Deno, where console output goes to the terminal and is therefore not interactive, the options parameter provides a way to customize the way the object is presented.
