What is the length of a string in JavaScript?
JavaScript does not return the length but rather returns the code units occupied by the string. It uses the UTF-16 string formatting methods to store characters. This essentially means that the characters in your string are encoded into a 16-bit long binary number before being stored.
What is the length in JavaScript?
In JavaScript, length is a string property that is used to determine the length of a string. Because length is a property of the String object, it must be invoked through a particular instance of the String class.
How do you find the length of a string?

(dot) operator.

How do you find length?
If you have the area A and width w , its length w is determined as h = A/w . If you have the perimeter P and width w , its length can be found with h = P/2−w . If you have the diagonal d and width w , it’s length is h = √(d²−w²) .
