JavaScript Strings

JavaScript strings are useful for holding data that can be represented in text form. Primitive strings are string literals (single or double quotes) and strings returned from String(‘string’) without the use of the new keyword.

There is a difference between string primitives and String objects. JavaScript will automatically convert primitive strings to string objects when a method needs to be invoked on a primitive string or a property lookup occurs by boxing (wrapping) the string primitive with the String object.
