Crockford then found that JavaScript could be used as an object-based messaging format for such a system. The system was sold to Sun Microsystems , Amazon.com , and EDS . JSON was based on a subset of the JavaScript scripting language (specifically, Standard ECMA -262 3rd Edition—December 1999 [ 11 ] ) and is commonly used with JavaScript ...
A property, in some object-oriented programming languages, is a special sort of class member, intermediate in functionality between a field (or data member) and a method.The syntax for reading and writing of properties is like for fields, but property reads and writes are (usually) translated to 'getter' and 'setter' method calls.

In JavaScript, an object is an associative array, augmented with a prototype (see below); each key provides the name for an object property, and there are two syntactical ways to specify such a name: dot notation (obj.x = 10) and bracket notation (obj["x"] = 10). A property may be added, rebound, or deleted at run-time.
In Object Pascal, a property is an exposed value that can either be linked to a class-field or a class-member method. The consumer does not know if the property is explicitly linked to a field or a writer method. Smart Pascal introduces a technique called "property expressions".
Instance variables are created when an object is instantiated, and are accessible to all the constructors, methods, or blocks in the class. Access modifiers can be given to the instance variable. An instance variable is not a class variable, [4] although there are similarities. Both are a type of class attribute (or class property, field, or ...
For each field, an "increment_group" option is set. This allows fields such as last/first to be incremented together, as long as they're in the same group. One field in each group should also have an "increment_button" option set - this field will have a button next to them to increment them. The name of the field should contain "<N>", which ...
