JavaScript

The key differences between Java and JavaScript are that Java is an OOP programming language, while JavaScript is an OOP scripting language. Java creates applications that run in a virtual machine or browser, while JavaScript code is run on a browser only. Java code needs to be compiled, while JavaScript code is all in text.

JavaScript is a dynamic, interpreted programming language. It is primarily used for developing the interactive front-end of web applications, but you can also use it in back-end development in tandem with Node. It is a client-side programming language, JavaScript's most common use is front-end web development, improving the user interface and interactivity for websites. Developers also use JavaScript beyond the web, to develop games, mobile applications, and server applications.

Start with the basics in this course, which includes:

• Introduction to JavaScript
• How to work with HTML + CSS + JavaScript together
• Building core concepts
• Language syntax
• Writing your first few programs
• Algorithmic practice with JavaScript
• And finally, a bunch of projects at the end to solidify your learnings.

One needs to have a knowledge of JavaScript concepts those will be the only common concepts that any framework or library they might depend on. The core concepts include functions, operators, and data structures. And they should include experience with at least one JavaScript framework or core library, such as React for building interactive websites or NextJS for backends. If their focus is back-end development, concepts such as API design and integration, data modeling, server-side rendering, and database querying are a must, as these will be part of the developer's daily tasks. Front-end developers should learn about web standards, the DOM API, web components (or lightning web components if you're working with the Salesforce ecosystem), and have some basic understanding of UX.

To excel in the field of JavaScript, candidates must possess certain skills that will enhance their learning and career. Some of the preferred skill-sets for JavaScript are:

• Basic knowledge of computer programming languages

• Interest in software and software building

• Knowledge of operating systems

• Critical Thinking

• Industry Skills

• Teamwork

• Communication Skills

• Willingness to Learn

While JavaScript is a powerful and versatile language that forms the backbone of modern web development, it is still advised to keep upgrading your resume with more and more modern tools, languages, and relevant projects. Individuals having relevant degrees in programming, like BTech and BCA, should not just settle on one programming language in the rising competition for even entry-level jobs. Pairing up your JavaScript skills with related technologies, frameworks, and practical project experience will significantly improve your chances of landing a job. A broader skill set is always preferred by some of the top recruiters for JavaScript and other programming languages jobs.

Generally, it is advisable to learn HTML first, and after that, one should move to learning JavaScript because HTML is foundational in its approach to creating websites, while JavaScript is essentially used to enhance the developed websites. HTML provides the content and structure, while JavaScript adds the dynamic functionality. For a complete and interactive website, both are necessary. Both languages are not exactly comparable as they serve different functions and are rather needed to carry out complementary purposes.

There is no fixed pre-requisite for admission to JavaScript courses. However, students should score a good percentage in the intermediate or class 12th to get admission in a certified JavaScript course.
