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.

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.

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.

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.

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

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 doesnt 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.

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 Its 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

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.
