The length of the String object's value measured in characters.
All String objects inherit properties and methods from the String prototype object. They will all return a value as a result of requesting the length property.
The length value of a String object is immutable.
This suggests that changing the value of a String object actually creates a new String object. This explains why continual string concatenations and modifications can sometimes cause a JavaScript execution to leak large amounts of memory as it runs.
