Object: The Object data type is defined by the Object class. The Object class serves as the base class for all class definitions in ActionScript. Objects in their basic form can be used as associative arrays that contain key-value pairs, where keys are Strings and values may be any type. RegExp: A regular expression object for strings.
An Array is a JavaScript object prototyped from the Array constructor specifically designed to store data values indexed by integer keys. Arrays, unlike the basic Object type, are prototyped with methods and properties to aid the programmer in routine tasks (for example, join, slice, and push).
In computer programming, foreach loop (or for-each loop) is a control flow statement for traversing items in a collection. foreach is usually used in place of a standard for loop statement.
In JavaScript, objects are garbage collected if they are unreachable from the global object. [4] One way to make an object unreachable is to overwrite the variables or properties that reference it. let x = {}; // The variable x is declared and set to an object x = null ; // x is overwritten and the object becomes unreachable
A JSON Patch document is structured as a JSON array of objects where each object contains one of the six JSON Patch operations: add, remove, replace, move, copy, and test. This structure was influenced by the specification of XML patch. The syntax looks like this: [1] [2]
