JavaScript has a different heritage than most other programming languages. JavaScript’s object system is prototype-based, not class-based. A JavaScript object is simply a collection of name (key) and value pairs. When it comes to inheritance, JavaScript has only one construct: objects. Each object has a private property that is linked to other objects called its prototype.

A GET request is typically used for things like AJAX calls to an API, while a POST request is typically used to store data in a database or send data through a form.
GET requests have limited security and can be seen by the user in the URL, while POST requests use two steps and are not visible to the user. Therefore, POST requests are more secure.

A DOCTYPE is an instruction to the web browser about which version of the markup language the page is written in. The DOCTYPE statement must be the first thing in your HTML document before the tag.

Cookies allow applications to store data on the client’s browser. The session save property allows the application to save data until the window is closed. The local storage facility allows applications to store data indefinitely.
A thread-local object is an object stored in a dedicated structure, associated with the current thread ID. Flask internally uses thread-local objects so that the user does not need to pass an object to a function to work in a request to remain threadsafe. Additionally, storing threads locally makes your logger reference global, but only within the current thread. This approach is useful, but requires a valid request context for dependency injection or when trying to reuse code that uses a request-oriented value.
Lazy loading is a design pattern commonly used in computer programming to delay the initialization of an object until it is needed. If used properly and properly it can contribute to the running performance of the program. Additionally, it is a loading code as soon as the user needs it. For example, there is a button on the page that displays a different layout after the user presses it. Therefore, there is no need to load the code for that layout on initial page load.
Both ID classes and selectors are used as hooks for CSS styles. IDs are typically used to style elements that are only seen once on a page, such as once in a navigation menu. Classes are similarly used to style various elements, such as the presence of links.
React Front End Developer Interview Questions (with Answers)
Event delegation refers to the process of using event extensions to handle events at a higher level of the DOM than the element where the event originates. This allows you to avoid adding event listeners to separate nodes; Instead, you can add an event listener to the parent element.
AJAX (Asynchronous JavaScript and XML) allows applications to asynchronously transfer data to/from a server without refreshing the page. This means that it tends to update parts of a web page without reloading the entire page. For example, your new Gmail messages arrive and are marked as new even if you haven’t refreshed the website.
Event bubbling is a type of event expansion where the event first activates a deeper target element. This causes all child node events to be automatically forwarded to their parent nodes. The advantage of this approach is speed because the code only has to traverse the DOM tree once.
A closure is an array of functions bound together by references to its closure state. This gives you access to an extension of an external function from an internal function. When a function creates a function, the concept of closure becomes more relevant. An interpreted function has access to variables that are not in the global scope, but exist individually in its closure.
