By their nature, strings do not have lengths in in pixels or something like that. Strings are data structures totally abstracted from the way they are presented, such as fonts, colors, rendering styles, geometrical sizes, etc. Those are all some properties of some UI elements, whatever they are.
The length property returns the length of a string. The length property of an empty string is 0.
The length of a string in JavaScript can be found using the . length property. Since . length is a property it must be called through an instance of a string class.
The length read-only property of a string contains the length of the string in UTF-16 code units.
You can create some inline element (span, for example), set your string as element's content (innerHTML), insert it into document (append to some element) and get it's width (clientWidth).
There is no other way to measure length of string in pixels because it depends on font style.
