2. TypeScript VS JavaScript
The two top technologies that are essential for developing web applications are TypeScript
and JavaScript. As a result, among the wide community of developers, JavaScript has become
the most well-liked programming language.
But since TypeScript was developed, the situation has drastically changed. Are you able to?
Considered to be a more advanced version of JavaScript with some extra capabilities is
TypeScript.
We must first comprehend the fundamental ideas behind TypeScript and JavaScript before
we can understand how they differ from one another.

3. What is JavaScript?
JavaScript is a dynamic computer programming language.
Its implementations enable the client-side script to interact
with users and create dynamic pages, and it is most
frequently used as a component of web pages. It is an
object-oriented programming language that may be
interpreted.
LiveScript was the original name of JavaScript, but
Netscape changed it to JavaScript, maybe in response to
the buzz that Java was causing. LiveScript, the
predecessor to JavaScript, had its debut in Netscape 2.0 in
1995. Netscape, Internet Explorer, and other web browsers
all contain the general-purpose language's core.

4. What Is JavaScript Used For?
One of the best scripting languages for developing dynamic and interactive web-content-like
apps in Javascript. The most widely used scripting language, JavaScript, is used on about
97% of all websites.
For creating various applications, such as software, hardware controls, and servers, JavaScript
is a godsend. In addition, JavaScript is regarded as a well-known web-based language
because of the way that it interacts naturally with web browsers.
● Easily adding impressive behaviour to create interactive web pages.
● Creating web and mobile apps.
● Building web servers and developing server applications.
● Speeding up the performance of the application.
● Developing front-end development as well as back-end development.
● Performing the data structure and validation on the web browser itself rather than on the
server.

5. What is TypeScript?
TypeScript is an open-source language created by
Microsoft that swiftly compiles JavaScript. TypeScript is a
suite of technologies that makes web development simpler
in addition to being a scripting language.
With additional capabilities specifically added to get
around limitations in JavaScript libraries, TypeScript is
JavaScript. It is advantageous for developers to have a
foundational understanding of static type definitions and
manage code complexity before using TypeScript. And it's
crucial to comprehend the distinction between TypeScript
and JavaScript.

6. What is TypeScript Used For?
Developers may create and supervise complex JavaScript applications using TypeScript, a
superset of typed JavaScript. It is essentially JavaScript with the addition of strong static
typing, code compilation, and object-oriented programming, to put it simply.
● Simplifying JavaScript code, making your application easier to read and debug.
● Quickly building web applications using highly productive web development tools for
JavaScript IDEs and practices, like static checking.
● Quickly coding for all complex and large applications.
● Availing all the benefits of ES6 (ECMAScript 6), plus more productivity.
● You can develop mobile and web applications with a TypeScript web development
company.

7. How Does TypeScript Differ from JavaScript?
● Typescript is a superset of JavaScript, while JavaScript is a scripting language that
makes it possible to create dynamic web pages.
● JavaScript code does not require compilation, whereas Typescript code does.
● When TypeScript and JavaScript are compared, TypeScript supports prototyping,
whereas JavaScript does not.
● In contrast to JavaScript, Typescript employs concepts like types and interfaces to
describe the data being used.
● JavaScript is the best choice for small projects, while Typescript provides a robust type
system with generics and JS capabilities for larger projects.

8. Pros and Cons of TypeScript
Pros Cons
It is an object-oriented language that supports strong static
typing
Unlike JavaScript, TypeScript is not a true statically typed
language. In fact, TypeScript supports dynamic typing.
Easily detect bugs or errors at the compile stage Supports enhanced code readability
With TypeScript, everything stays the way it was initially
defined.
TypeScript typically requires code compilation at every
phase
TypeScript codes are more self-expressive Unit tests are no longer instant
Rich IDE (Integrated Development Environments) support Non-TS libraries require types

9. Pros and Cons of JavaScript
Pros Cons
just-in-time (JIT) compiled language
JavaScript code is viewable to the user, making it used for
malicious purposes.
Compatible with all modern web browsers, such as Safari,
Google Chrome, Opera Firefox, and Internet Explorer.
The browser interprets JavaScript differently in different
browsers. Thus, the code must be run on various platforms
before publishing.
Interoperable: meaning that we can use it with other
programming languages like Node JS, AngularJS, and
others and embed it in web pages.
Many HTML editors support debugging, it is not as efficient
as other editors like Visual studio code or C/C++ editors.
Also, as the browser doesn’t show any error, it is difficult for
the experienced developer to detect the problem.
Versatile and dynamic language
A single code error can stop the rendering of the entire
JavaScript code on the website.
Minimizes the code length
The continuous conversions take longer in the smooth
transition of a number to an integer.

10. Difference Between Typescript and Javascript: The
Comparison Table
JavaScript is a programming language that helps in the creation of interactive web pages,
whereas TypeScript is a modern JavaScript development language. In contrast to JavaScript,
which lacks such a concept, TypeScript employs ideas like types and interfaces to describe
the data being used.
It's time to examine the idea of comparing TypeScript with JavaScript after looking at the
fundamentals of both languages. So let's analyze how JavaScript and TypeScript vary by
using a comparison table.

11. Features TypeScript JavaScript
Type Strongly-typed object-oriented programming language
Light-weight, interpreted programming
language
Creator Anders Hejlsberg Brendan Eich
Server Type Client-side Client-side and server-side
Best For Developing large or complex applications Developing small-sized applications
Compiler
Code compilation converts your TypeScript code to
JavaScript code
It’s completely an independent language
Learning curve Steep learning curve
Easy to learn JavaScript and has stiff
learning curve
Supports Supports modules, generics, and interfaces
Does not support modules, generics, or
interfaces
Prototyping Prototyping feature is available No support of Prototyping

12. When to Choose JavaScript?
Small Projects: If you're working on a small web project or there aren't many available codes,
JavaScript is a great alternative.
Active Framework Support: The developers might not be able to incorporate all the features
into the same code if TypeScript does not support any commonly used frameworks like
EmberJS.
Build Tools: TypeScript needs a build step when professionals need to create the JavaScript
application's final run. However, developing JavaScript applications without any build tools is
becoming increasingly unusual.
Testing Workflow: The advantages of switching to TypeScript could not exceed the costs if
JavaScript experts are working on test-driven web development projects.

13. When to Choose TypeScript?
Compile Time Type Checking: Vanilla JavaScript is typically supported by TypeScript, and in
such instances, type verification is carried out during runtime. It gradually increases the
code's runtime overhead, which can be reduced by doing compile-time validation.
Large-Scale Projects: Programming languages like TypeScript are specifically made for
creating complex systems that function well on a big scale or when numerous Typescript
developers are working.
Easy to Use: You can make use of IntelliSense, which helps in identifying and navigating new
interfaces if the professionals have engaged in React or Node JS development but are
unfamiliar with its APIs. However, they both offer type definitions.

14. TypeScript VS JavaScript: Which is Better?
The developers can deal with removing some software irregularities during the web
development project phase more easily by choosing TypeScript over JavaScript. Additionally,
you can quickly safeguard the source code before releasing it for use.
We have seen the general idea of the main features that are available in both technologies in
this essay comparing TypeScript vs JavaScript. In addition, we discovered the numerous
optional options or terminology describing the differences between Javascript and
Typescript.
