An array is an ordered collection of values. When calling JSON.stringify() you can pass a function as a second argument. The JSON.parse () method parses a JSON string, constructing the JavaScript value or object described by the string. reviver Optional. If the HTTP method is one that cannot have an entity body, such as GET, the data is appended to the URL.. The dicts contain various key/value pairs, all strings.

JSON object consist of curly braces ({ }) JSON text/object can be converted into Javascript object using the function JSON.parse(). Parameters are essentially passed to functions by value so if the code within the body of a function assigns a completely new value to a parameter that was passed to the function, the change is not reflected globally or in the code which called that function..

We have called createStudent () from the main () method. This constructs a new function object at run-time. Reuse and pass them around without fear of mutating another instance. Example, two different functions, add and multiply, are passed as a library each.
