Standard Objects

Standard objects are Objects that are native (or included) in JavaScript. Things like Math, Infinity, Boolean, String

Although JS has the primitives types these are not able to have properties attached to them like object would. So these Standard object actually work behind the scene to help the developer extend the use of primitives.

Plain Text

This is valid JS. Although this shouldn't be possible because the primitive boolean shouldn't have any object properties.

true.toString()

What JS is doing behind the scenes is:

Boolean(true).toString()

This then provides the appropriate object properties to turn the boolean into a string.
