Rest parameters are similar to Javascript's arguments object, which is an array-like object that contains all of the parameters (named and unnamed) in the current function call. Unlike arguments , however, rest parameters are true Array objects, so methods such as .slice() and .sort() can be used on them directly.
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.
JSON (JavaScript Object Notation, pronounced / ˈ dʒ eɪ s ən / or / ˈ dʒ eɪ ˌ s ɒ n /) is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of name–value pairs and arrays (or other serializable values).
JSON-LD (JavaScript Object Notation for Linked Data) is a method of encoding linked data using JSON. One goal for JSON-LD was to require as little effort as possible from developers to transform their existing JSON to JSON-LD. [1] JSON-LD allows data to be serialized in a way that is similar to traditional JSON. [2]
adds a value into an object or array. Remove removes a value from an object or array. Replace replaces a value. Logically identical to using remove and then add. Copy copies a value from one path to another by adding the value at a specified location to another location. Move
JavaScript Object Notation (JSON) is often used as an alternative format for data interchange, [15] although other formats such as preformatted HTML or plain text can also be used. [16] A variety of popular JavaScript libraries, including JQuery, include abstractions to assist in executing Ajax requests.

In July 2005, George Jempty suggested an optional variable assignment be prepended to JSON. [19] [20] The original proposal for JSONP, where the padding is a callback function, appears to have been made by Bob Ippolito in December 2005 [21] and is now used by many Web 2.0 applications such as Dojo Toolkit and Google Web Toolkit.
