To begin with, JavaScript is a scripting language that is useful in creating dynamic and interactive web content. In addition, it is a lightweight programming language that can calculate, manipulate and validate data.
Features Of JavaScript
JavaScript is capable of validating user inputs for errors and it checking the empty fields before sending the data over to the server. In addition, it is a client-side technology and can perform basic calculations on the browser without asking server time for every task. Thus, allowing a user to perform calculations quickly. Moreover, it comes with various browsers with functionalities that help in reducing server load and network traffic. JavaScript is platform-independent and it eliminates the problems of compilation and compatibility. It can run on various platforms such as Windows, Macintosh, and other Netscape platforms and can be embedded in another script like HTML.
In addition, it comes with a built-in function for handling date and time which allows a user to code only by using methods like. get Date (). Moreover, it can generate HTML content for the web, allowing users to add text, links, images, tables, etc. JS is a lightweight scripting language that facilitates data handling at the browser only. In addition, it consists of a limited set of libraries and deals with the client-side execution. It facilitates dynamic typing and defines the variable on the basis of the stored value. Moreover, it allows a user to a variable without worrying about its type by just using the “var” or “let” keyword before the variable name.

Benefits Of Using JavaScript
JS reduces the compilation time along with speeding up the program execution as it is an interpreted language along with being a client-side script. It is a simple language that is easy to learn and understand. In addition, it is extremely popular as it is very feasible to implement and works perfectly with other programming languages.

A developer can embed it into any webpage or inside the script of another programming language due to its high interoperability. Apart from these, given below are some of the benefits of using JavaScript.
- Server Load- It makes data validation possible on the browser rather than sending it off to the server as it operates on the client-side.
- Rich Interfaces- JS comes with various interfaces along with Drag & Drop components that give catchy look to the web pages.
- Extended Functionality- It saves time and money by allowing third-party add-ons o add snippets of predefined code in their code.
- Versatility- JavaScript can deal with both front-end as well as back-end development. Thus, making it a versatile scripting language.
- Less Overhead- It uses various built-in functions for loops, DOM access, Etc for reducing the code length & improving performance.
Is JavaScript a Good Career?
Yes, learning JS is definitely a wise choice as it is one of the best and most promising careers in the IT industry. This is because of the multiple uses of this scripting language.

Master the Fundamentals of JavaScript
Interpreted programming languages and compiled programming languages are the two main kinds of programming languages. JavaScript is an interpreted language, which implies that the program runs precisely as written from beginning to finish and start to end. In this case, the computer does not need to do the intermediary step of compiling the programming language.
In order to avoid confusion when the code is performed sequentially from beginning to end, you must prepare in advance. When following instructions, it is critical that they be done so in the right order. If a handful of phrases in the script are completed in the wrong order, the script will not operate properly. Instead, an error notice will be shown in the browser developer console, which is the environment in which your code will be executed.
