India has a long history of being a centre of technology, and it currently appears to be exploding in terms of app creation. According to a recent survey, the number of mobile applications being built in India has increased by 50% just in the last year. As per another report published by CB Insights, there are about 4 million jobs in the tech sector in India, and the demand for developers is expected to increase by 30% by the next coming years.
As a result, with the right skillset and the willingness to learn, your career as a web developer is bound to flourish.

In general, a developer must possess strong coding skills and be able to communicate effectively with both technical and nontechnical people. A good programmer needs to be analytical and creative, with excellent problem solving abilities.
Technology is evolving at a lightning pace. Everything in our modern world is dependent on data. New innovations emerge from Silicon Valley every day. A.I., ML, and VR are all examples of such technology. People who are able to code are in high demand at all times due to the rapid pace of technological innovation. Having strong knowledge of many languages and frameworks is essential. They must also be able to switch between browsers and operating systems with ease. Someone needs to be able to use the finished product in addition to writing code. Furthermore, they may run tests on their code and fix bugs as they find them.
Types of JS Developers
Front End Developer
This kind of developer mostly works on a website or app’s front end. Their main job is to design and build user interface elements, such as buttons, forms, dropdowns, navigation menus, search boxes, and so on. They also take care of styling these elements using CSS. The front end developer may also be tasked with developing responsive layouts and designing pages that can adapt to any screen size.
Back End Developer
This type of developer works primarily behind the scenes. They are responsible for writing server side scripts that handle requests from the browser. These include things like authentication, authorization, database management, caching, security checks, etc.They may also be required to write APIs (Application Programming Interfaces) which allow other applications to access the backend services provided by the web app.
This person must be comfortable working across multiple platforms and operating systems while maintaining solid coding standards. They should be familiar with modern programming languages like Java, Python, Ruby, PHP, and SQL.
The ideal candidate will have excellent communication skills, be organized, self motivated, and passionate about technology. You’ll want someone who can quickly learn new technologies and keep up with the latest trends.
You’ll be working with a group that values good design, testing, documentation, and continuous improvement. You will be expected to communicate effectively with clients, peers, and management.
JScript developers’ responsibilities
So how do you choose one way over another? Well, I’d say you really just need to ask yourself whether you want to focus on making something work properly or make something look cool.
Take it slow at first- If you are a beginner, you might want to avoid starting off with the most popular frontend framework like React or AngularJS. These frameworks come with tons of documentation and tutorials, which makes it easy for you to get stuck into something that isn’t really what you’re looking for.
Instead, you should start off with basic data types and functions. For example, you could start off with HTML5 data attributes and add some CSS3 styles to make things look nice. Or maybe you’d like to use a library called jQuery to perform DOM manipulation. Whatever you choose, you’ll find plenty of resources online to help you along the way.
When you have a firm grasp on the fundamentals, you can then go on to studying how to create apps that run on the server. If you don’t know much about programming, you could start out with PHP. But don’t worry – there’s lots of resources online to help teach you.
- Number: It represents numbers like integers, floating point numbers etc.
- String: It represents strings.
- Boolean: It represents true/false.
- Null: It represents null.
- Undefined: It represents undefined.
- Object: It represents any type of data.
- Array: It represents ordered collection of items.
- Function: It represents a function.
- Date: It represents date and time.
- RegExp: It represents regular expression.
- Error: It represents error.
- Global scope: It refers to all the global variables.
- Local scope: It refers to local variables declared inside a function.
- Closure scope: It refers to variables defined within a block of code.
How do Function declaration and Function expression differ?
- A function declaration creates a new function while a function expression returns a value.
- A function declaration always takes arguments while a function expression may take or omit them.
- A function declaration cannot be invoked directly while a function expression can be called using ().
- A function declaration is hoisted while a function expression is not.
- A function declaration allows us to pass parameters while a function expression requires us to specify values when calling it.
- A function declaration is evaluated before being assigned to a variable while a function expression is evaluated after being assigned to a variable.
- A function declaration is created on the fly while a function expression is created once and then reused.
- A function declaration is visible only within its own scope while a function expression isvisible across different scopes.
- Inline Scripting: This method involves embedding script tags into the HTML page itself.
- External Scripts: This method involves linking external scripts from other sites.
- Client Side Includes: This method involves including the contents of another document into your current one.
- Server Side Includes: This method includes the contents of another document onto your server.
XML documents have two parts:
- Document Type Definition (DTD), which defines what elements are allowed in the document and
- Element Declaration, which describes how the element should look.
The DTDis optional but if present, it must be included in the same file as the element definition.
The element definition contains attributes that describe the element. Attributes are name/value pairs.
What is Ajax?
It is a way to send data from the browser to the server without having to refresh the entire page.
What is JSON?
JSON is a lightweight data-interchange format. It is easy to read and write, human-readable, compact, and platform independent.
Finally, you’ll look at some common APIs such as DOM manipulation, AJAX and databases. After completing this course at FITA Academy, you will have all of the knowledge necessary to create web applications that are reliable and scalable.
