The world revolves around the Internet. Websites require content to display some relevant information on the Internet. To design these, Javascript (JS) is used. JavaScript is used to design Web Pages in a more interactive way, and in interesting manner. JavaScript can also be incorporated with Best Data Structures and Algorithms Course

What are Data Structures and Algorithms?
Now we’ll have a look into the definition of Data Structures and Algorithms (DSA). Data structures are ways of organizing data so that it can be accessed and modified efficiently. This involves collecting data values, establishing relationships among them, and providing functions or operations that can be applied to the data.

Javascript
We’ll now jump into the concept of Javascript.

What is Javascript?
JavaScript is a lightweight programming language that web developers commonly use to create more dynamic interactions. This includes developing web pages, applications, servers, and even games. Developers generally use JavaScript alongside HTML and CSS. The scripting language works well with ...
... CSS in formatting HTML elements. However, JavaScript still maintains user interaction, something that CSS cannot do by itself.

What is JavaScript Used For?
JavaScript is a versatile scripting language that helps ensure web pages are compatible with different browsers and devices. JavaScript has continued to evolve along with new browsers like Mozilla Firefox and Google Chrome. In fact, Google Chrome even developed the first modern JavaScript engine, called V8, which compiles bytecode into native machine code. JavaScript was originally only used on the client side but has since been used on the server side as well after the development of Node.js. Node.js is a cross-platform server environment that runs on the Google Chrome JavaScript V8 engine.
Some of the basic uses of JavaScript are as listed below.

i) Web and Mobile Applications
Developing JavaScript frameworks - consisting of JavaScript code libraries, which enable developers to use pre-written code in their projects. This saves time and effort that would otherwise be spent coding programming features from scratch.

ii) Building Web Servers and Server Applications
Node.js lets you use JavaScript to build web servers and back-end infrastructure, which can save you time and effort. Would you like to develop a basic HTTP server that displays plain text when users access a web page? The built-in HTTP module makes this possible. Would you like to develop a basic HTTP server that displays plain text when users access a web page? The built-in HTTP module makes this possible. You can use either the Node.js own web server, Node-OS, or third-party ones like Microsoft Internet Information Services (IIS) and Apache to handle the HTTP requests.

iii) Game Development
JavaScript is a powerful tool that can help you build amazing games when used with HTML5 and an Application Programming Interface (API) like WebGL. There are plenty of great JavaScript-based game engines out there like Phaser, GDevelop, and Kiwi.js that can help with rendering graphics, recycling code, and creating cross-platform applications. The best examples for this context are Angry Birds, 2048, etc.

Data Structures in JavaScript (JS):
There are several different types of data structures that can help you solve coding problems efficiently. This can reduce the amount of time you need to spend programming, as you can simply store and retrieve data using these structures. However, it's important to note that each data structure is designed for specific purposes. This means that the surrounding code must be written properly in order for the data within the structure to be accessible.

JavaScript supports four basic data structures: arrays, queues, linked lists, and trees.

i) Arrays
Storing data in memory for later use is called an array. Arrays have a fixed number of cells and each cell has a numeric index. To select data from an array, you use the index number.
ii) Queues
A queue is a sequential structure that processes elements in the order in which they are entered, often referred to as FIFO (First In, First Out).
iii) Linked Lists
Linked lists store data using a reference system with elements stored in nodes linked by pointers. This makes it easy to index data rather than position elements.
iv) Trees
Trees are a type of structure where the Roots branch off the top into other, related Child Nodes below.

Why is JavaScript (JS) a Good Platform for Algorithms?
JavaScript is a great language for beginners to learn coding with. It teaches you the basics, like working with variables, arrays, objects, loops, and functions. Once you have a good understanding of these concepts, you can start writing algorithms. Algorithms allow you to manipulate strings, and factorial numbers and make advanced calculations.
Some popular algorithms used in JavaScript include Big-O notation, recursions, searching algorithms, sorting algorithms, and others. JavaScript is a great client-side programming language for easily executing most data structure algorithms.

Advantages of JavaScript
i) Speed
JavaScript is a great choice for programming because it is an interpreted language, which means it doesn't need to be compiled like other languages like Java. Plus, it is a client-side script, so it will execute faster since there is no need to connect to a server.


ii) Simplicity
JavaScript is easy to understand and learn. Its simple structure is user-friendly for both users and developers. It is also very feasible to implement, saving developers money on developing dynamic content for the web.
iii) Popularity
JavaScript is a widely used programming language that is supported by all modern browsers. Many well-known companies use JavaScript, including Google, Amazon, and PayPal.
iv) Interoperability
Many developers prefer to use JavaScript because it works well with other programming languages. It can be embedded into any webpage or script, making it a versatile tool for developing applications.
v) Server Load
JavaScript operates on the client side, which means data validation can be done on the browser itself instead of sending it to the server. If there's any discrepancy, the whole website doesn't need to be reloaded. The browser can just update the selected segment of the page.

Disadvantages of JavaScript (JS)
i) Client-Side Security
Since the JavaScript code is viewable to the user, it's possible for others to misuse it for malicious purposes. This might include using the source code without authorization. Additionally, it's easy to place code on the site that compromises the security of data.

ii) Browser Support
The browser interprets JavaScript differently in different browsers. Thus, the code must be run on various platforms before publishing. The older browsers don’t support some new functions and we need to check them as well.
