Example of strings are ‘This is a string’ and “This is another string”. Numeric values – 1, and 3.1416. Boolean values – true or false. On the other hand, reference types are different. They include objects (including JS built-in objects), Arrays, and functions. Essentially, they can have any number of properties or elements with various types (both primitives and references), so they cannot be manipulated as easily as fixed-size primitive v Continue Reading
