Difference between JavaScript and TypeScript

JavaScript vs TypeScript

JavaScript is the most popular and used programming language in Web development. TypeScript is a superset of JavaScript and is getting popularity when building Web applications. While TypeScript is a superset of JavaScript, it brings many benefits for software developers that can help them build Web apps faster and in more organized way. In this blog, let’s see the difference between TypeScript and JavaScript and compare JavaScript and TypeScript features.

JavaScript

JavaScript is the most popular programming language for Web development. JavaScript also known as JS is a high-level interpreted scripting programming language that is used in Web development. Unlike other popular programming languages that use a compiler to compile the language, JavaScript uses an interpreter to convert JavaScript to machine code.

JavaScript’s proposal was designed by Brendan Eich in 10 days in May 1995. The first official name of JavaScript was LiveScript and was shipped in Netscape Navigator 2.0. JavaScript originally managed by Netscape is currently managed by Mozilla Foundation. In 1997, JavaScript was accepted by ECMA International and became a standard. The current version of JavaScript is ECMAScript 2019.

Characteristics

Here are the key characteristics of JavaScript:

  1. JavaScript is a high-level scripting programming language.
  2. JavaScript is a multi-paradigm programming language and supports event-driven, functional, and imperative programming styles. Structured programming syntax in JavaScript is similar to C language and supports common statements including if statement, while loops, switch statements and do while loop.
  3. While JavaScript majorly runs on the client-side in the user’s browser, but it can run on the server-side and today there are several JavaScript-based libraries and frameworks are available.
  4. JavaScript combined with HTML and CSS makes a majority of the Web pages on the Web. While HTML and CSS combo is used to build Web pages (user interfaces), JavaScript is used for functional coding.
  5. Majority of the Web browsers including Google Chrome, Microsoft Edge, Apple Safari, and Mozilla Firefox fully support JavaScript.
  6. JavaScript is a dynamically typed language that means the type of an object or variable is decided at runtime and the same variable can be used to store different types and values.
  7. While JavaScript is not a fully object-oriented programming language but is almost objects-oriented. JavaScript has concepts of objects, properties, and functions. Inheritance in objects is supported via prototypes.
  8. Function is a first-class member of JavaScript. That means, a function is considered to be an object and can have its own properties and methods.

TypeScript option you want to enable beyond strict : noUncheckedIndexedAccess

strict (and its sub flag strictNullChecks) can really help prevent null and undefined errors in your runtime #JavaScript. However, it doesn't defend against invalid array and object access.

In this lesson we look at a flag that protects against rogue undefined that might end up in your #TypeScript if this flag is not enabled

What is JavaScript - Stackfindover - Blog

Who invented JavaScript, how it works, as we have given information about Programming language in our previous article ( What is PHP ), but today we will talk about what is JavaScript, why JavaScript is used The Answers to all such questions and much other information about JavaScript, you are going to get here today. Hope this information will work for you.

Who invented JavaScript?

JavaScript language was invented by Brendan Eich in 1995. JavaScript is inspired by Java Programming Language. The first name of JavaScript was Mocha which was named by Marc Andreessen, Marc Andreessen is the founder of Netscape and in the same year Mocha was renamed LiveScript, and later in December 1995, it was renamed JavaScript which is still in trend.

What is JavaScript?

JavaScript is a client-side scripting language used with HTML (Hypertext Markup Language). JavaScript is an Interpreted / Oriented language called JS in programming language JavaScript code can be run on any normal web browser. To run the code of JavaScript, we have to enable JavaScript of Web Browser. But some web browsers already have JavaScript enabled.

Today almost all websites are using it as web technology, mind is that there is maximum scope in JavaScript in the coming time, so if you want to become a programmer, then you can be very beneficial to learn JavaScript.

JavaScript Hello World Program

In JavaScript, ‘document.write‘ is used to represent a string on a browser.

<script type="text/javascript">
	document.write("Hello World!");
</script>

How to comment JavaScript code?

  • For single line comment in JavaScript we have to use // (double slashes)
  • For multiple line comments we have to use / * – – * /

JavaScript vs TypeScript | JavaScript And TypeScript Difference | Full Stack Course

"This video on JavaScript vs TypeScript helps you understand the two languages and draw a comparison between them. JavaScript is a client-side scripting language while TypeScript is an OOP language developed to address the shortcomings of JavaScript. Although TypeScript supports all the features of JavaScript, they have significant differences. The following are the topics covered in this JavaScript vs TypeScript video -

What is JavaScript?
JavaScript is a scripting language that is used to create and manage dynamic web pages, basically anything that moves on your screen without requiring you to refresh your browser. It can be anything from animated graphics to an automatically generated Facebook timeline. When most people get interested in web development, they start with good old HTML and CSS. From there, they move on to JavaScript, which makes sense, because, these three elements together form the backbone of web development. HTML is the structure of your page like the headers, the body text, any images you want to include. It basically defines the contents of a web page.
CSS controls how that page looks (it’s what you’ll use to customize fonts, background colors, etc.). JavaScript is the third element. Once you’ve created your structure (HTML) and your aesthetic vibe (CSS), JavaScript makes your site dynamic (automatically updateable).

What is TypeScript?
TypeScript is an object oriented programming language. It is a superset of JavaScript and was developed to inject OOP concept to develop bigger and more complex code. TypeScript adds external features like modules, namespaces, interface, generics and more to JavaScript. TypeScript is strongly and statically typed where the variables are known at compile time. This leads to better code completion, type checking, tooling, error handling and refactoring.
