Question 4

 In web development, “local storage” refers to what?

Answer 4

localStorage
 In web development, “local storage” refers to a web storage mechanism
that allows web applications to store data locally within a user’s web
browser. Local storage is part of the Web Storage API, which provides
two mechanisms for storing data: localStorage and sessionStorage. Both
of these mechanisms allow web applications to store data on the clientside (in the user’s browser) without the need for server communication.

Question 5

JSON (JavaScript Object Notation)

Answer 5

SON (JavaScript Object Notation)
 JSON is a lightweight data interchange format that is easy for humans to
read and write and easy for machines to parse and generate. It is often
used for data exchange between a server and a web application, as well
as for configuration files, data storage, and more. JSON is a text-based
format that consists of a collection of key-value pairs, where each key is a
string and each value can be a string, number, boolean, object, array, or
null.

Question 6

Asynchronous programming

Answer 6

Asynchronous programming
 Asynchronous JavaScript programming is a programming paradigm that
enables you to write non-blocking code to handle tasks that may take
some time to complete, such as making network requests, reading files, or
executing time-consuming operations. Asynchronous programming is
crucial in web development to ensure that web applications remain
responsive and don’t block the user interface while waiting for tasks to
finish.
