Creates a new inline group in the Web Console log. This indents following console messages by an additional level, until console.groupEnd() is called.

Note: This feature is available in Web Workers.

Syntax

console.group([label]);

Parameters

label
Label for the group. Optional. (Chrome 59 tested) Does not work with console.groupEnd().

Using groups in the console

Requires Gecko 9.0(Firefox 9.0 / Thunderbird 9.0 / SeaMonkey 2.6)

You can use nested groups to help organize your output by visually associating related messages. To create a new nested block, call console.group(). The console.groupCollapsed() method is similar, but the new block is collapsed and requires clicking a disclosure button to read it.

Note: From Gecko 9 until Gecko 51, the groupCollapsed() method was the same as group(). Collapsed groups are fully supported starting in Gecko 52. See bug 1088360.

To exit the current group, call console.groupEnd(). For example, given this code:

console.log("This is the outer level");
console.group();
console.log("Level 2");
console.group();
console.log("Level 3");
console.warn("More of level 3");
console.groupEnd();
console.log("Back to level 2");
console.groupEnd();
console.log("Back to the outer level");

The output looks like this:

See Using groups in the console in the documentation of console for more details.
