JS Output to Console

Console.log (object[, Object, ...])
Output a message on the console. If there are multiple parameters, the output is separated by a space.

The first argument can be a string that contains the formatted placeholder output, for example:

Console.log ("The%s jumped over%d tall buildings", animal, count);

The example above can be replaced with the following code with unformatted placeholder output:

Console.log ("The", Animal, "jumped over", count, "tall buildings");

Also, these two methods can be used in combination. If you use a format placeholder and you supply more arguments than the number of placeholders, the extra arguments are appended to the string in a space-delimited manner, like this:

Console.log ("I am%s and I have:", MyName, Thing1, Thing2, thing3);

If the parameter is a JavaScript object, then the console output is not static text, but an interactive hyperlink, click the hyperlink to view the object's HTML, CSS, Script, Dom window, can be formatted string%o instead of JavaScript object.

Console.log ("Body tag is%o", document.body);

To format a list of strings:

Formatting Strings	type
%s	String
%d,%i	Integral type (digital type is not supported temporarily)
%f	Floating-point type (digital type is not supported temporarily)
%o	Linked objects
