Ques:- What is the difference between REST and SOAP APIs
Asked In :-
Winsoft Technologies India Pvt. Ltd, Xoriant Solutions Pvt Ltd, DREAMORBIT SOFTECH PVT, AnAr Solutions, Trigent Software, iROID Technologies, Dhruvsoft Services, TNQ Technologies, Define Labs, Sun Technology Integrators,
Right Answer:
REST (Representational State Transfer) is an architectural style that uses standard HTTP methods and is typically more lightweight and easier to use, while SOAP (Simple Object Access Protocol) is a protocol that relies on XML for message format and has strict standards for security and transactions. REST is generally more flexible and faster, while SOAP is more suited for enterprise-level services requiring high security and reliability.

1. **GET**: Retrieve data from a server.
2. **POST**: Send data to a server to create a new resource.
3. **PUT**: Update an existing resource on the server.
4. **DELETE**: Remove a resource from the server.
5. **PATCH**: Apply partial modifications to a resource.
These methods define the action to be performed on the specified resource in the API.

Right Answer:
An API (Application Programming Interface) is a set of rules and protocols that allows different software applications to communicate with each other. It defines the methods and data formats that applications can use to request and exchange information. APIs work by sending requests from one application to another, which then processes the request and sends back a response.

Ques:- What is AJAX and how does it work
Asked In :-
Object Frontier Software, Addweb solutions, Priya Softweb Solutions, TNQ Technologies, Oodles Technologies, Recodem, Novalnet e-Solutions, SWYM, Happiest Minds Technologies Pvt., Keyideas Infotech,
Right Answer:
AJAX (Asynchronous JavaScript and XML) is a web development technique that allows web pages to communicate with a server and update content asynchronously without reloading the entire page. It works by using JavaScript to send requests to the server, which can return data (often in JSON or XML format) that the browser can then use to update the webpage dynamically.

Ques:- What are promises and async await in JavaScript
Asked In :-
Unyscape Infocom Pvt. Ltd., Medvarsity Online, Ziffity Solutions, LiteBreeze Infotech, CakeSoft Technologies, Sun Technology Integrators, Happiest Minds Technologies Pvt., Ray Business Technologies, XIPHIAS Software Technologies, Spark Infosys,
Right Answer:
Promises in JavaScript are objects that represent the eventual completion (or failure) of an asynchronous operation and its resulting value. They allow you to handle asynchronous code more easily by providing methods like `.then()` for success and `.catch()` for errors.
`async` and `await` are syntactic sugar built on top of promises. An `async` function always returns a promise, and within an `async` function, you can use `await` to pause execution until a promise is resolved, making the code easier to read and write as if it were synchronous.
