Object Oriented programming is focused on classes and objects. It COUPLES the data (attributes) to the methods inside classes and objects.
Functional programming is focused on methods. It SEPARATES methods from the data.
FP is good for situations where, as your application evovles, you are mostly adding new methods. SQL is a highly FUNCTIONAL language.
OOP is good for situations where, as your application evolves, you primarily are adding new data / attributes. Changing a method may require editing many different CLASSES.
The Google developers who wrote Angular created a service, a series of Javascript methods, that they named $http, to send and receive data from a server via HTTP requests.
The Angular version of HTTP requests looks like this:
$http.get('/someURL').
$http.post('/someURL'), {msg:'hello world!'}).
AJAX is HTTP requests happening behind the scenes of your web page, without re-loading the HTML page, to GET or POST data - often via JSON objects.
What is the difference?
A URI is a Unique/Uniform Resource Identifier. It could be compared to a Name (identifier). It is "a compact sequence of characters that identify an abstract or physical resource." Sometimes people even refer to it as a URN.
A URL is a Unique/Uniform Resource Locator. It is the item's name AND its location. It is a "subset" of URIs that, in addition to giving the resource a name/identity, also provide a way to locate it.
