JavaScript FAQs:


What is JavaScript?

JavaScript is a text-based programming language used both on the client-side and server-side that allows you to make web pages interactive. Where HTML and CSS are languages that give structure and style to web pages, JavaScript gives web pages interactive elements that engage a user. Common examples of JavaScript that you might use every day include the search box on Amazon, a news recap video embedded on The New York Times, or refreshing your Twitter feed.

Incorporating JavaScript improves the user experience of the web page by converting it from a static page into an interactive one. To recap, JavaScript adds behavior to web pages.


What is JavaScript used for?

JavaScript is mainly used for web-based applications and web browsers. But JavaScript is also used beyond the Web in software, servers and embedded hardware controls.

Why use JavaScript over other programming languages?

Aside from the unlimited possibilities, there are many reasons for web developers to use JavaScript over other programming languages:

  • JavaScript is the only programming language native to the web browser
  • JavaScript is the most popular language
  • There’s a low threshold to get started
  • It’s a fun language to learn


Why should I learn JavaScript ?

The most obvious reason for learning JavaScript is if you have hopes of becoming a web developer.

Even if you haven't got your heart set on a tech career, being proficient in this language will enable you to build websites from scratch—a pretty useful skill to have in today's job market!
if you learn it, you'll be able to build not just modern web applications but also any applications for any device and platform. In addition, you probably have noticed how technologies as a whole are changing.

Is JS and HTML the same?

JavaScript is an advanced programming language that makes web pages more interactive and dynamic. HTML is a standard markup language that provides the primary structure of a website. JavaScript simply adds dynamic content to websites to make them look good.

React. js is an open-source JavaScript library that is used for building user interfaces specifically for single-page applications. It's used for handling the view layer for web and mobile apps. React also allows us to create reusable UI components.

React allows developers to create large web applications that can change data, without reloading the page. The main purpose of React is to be fast, scalable, and simple. It works only on user interfaces in the application. This corresponds to the view in the MVC template.

Learn more about React Training Course 

Our React training course is practical and you will build components and applications with real-world applicability, right from the start.

We will build against tests from the end of day one, and design sensible component-based solutions using best practice. You will also gain an awareness of the wider JavaScript toolchain ecosystem including Node, Karma and Webpack. Flux is an architectural pattern characterised by one-way data flow, immutability and message passing. In the course, we create a central data store and then pass messages to it, telling it how to change. Changes then flow into the component tree and update the DOM. This can seem intimidating at first but it quickly becomes natural. We use Redux for Flux, which is currently the best practice solution.




Is React a language?

React is a popular and widely used programming language at present since almost every web developer or a full-stack developer is using it.

Why use React?

React is a declarative, efficient, and flexible JavaScript library for building user interfaces. It lets you compose complex UIs from small and isolated pieces of code called “components”. React has a few different kinds of components, but we'll start with React.Component subclasses: class ShoppingList extends React.

Is React HTML?

What makes React such a desirable library to learn is that it doesn't replace HTML. It takes advantage of HTML's popularity and strength as the most popular programming language, by letting you use a very similar syntax to HTML to build interfaces and add dynamic features to it using JavaScript.

How does React work?

React uses a declarative paradigm that makes it easier to reason about your application and aims to be both efficient and flexible. It designs simple views for each state in your application, and React will efficiently update and render just the right component when your data changes.

Is React front-end or backend?

ReactJS is an open-source, component-based front-end library responsible only for the view layer of the application. It is maintained by Facebook.

Does React use JavaScript?

React is just JavaScript, there is a very small API to learn, just a few functions and how to use them. After that, your JavaScript skills are what make you a better React developer. There are no barriers to entry. A JavaScript developer can become a productive React developer in a few hours.

Should I learn JavaScript or React?

Since React is a JS library, there is no way around learning JavaScript. You cannot learn React without JavaScript or without knowing JavaScript in the first place. In comparison to other frontend solutions, React makes heavily use of JavaScript.

Why React is famous?

One of the most known features of React is its ability to leverage the benefits of Search Engine Optimization (SEO). By using React, businesses can considerably reduce page load times and start ranking higher in search engines (a.k.a. Google, Bing, Yahoo, etc).



About Typescript

TypeScript is a programming language developed and maintained by Microsoft.

It is a strict syntactical superset of JavaScript and adds optional static typing to the language. TypeScript is designed for the development of large applications and transcompiles to JavaScript.

What are the main features of TypeScript?

Features of TypeScript

  • TypeScript is just JavaScript. TypeScript starts with JavaScript and ends with JavaScript.
  • TypeScript supports other JS libraries.
  • Compiled TypeScript can be consumed from any JavaScript code. .
  • JavaScript is TypeScript. This means that any valid .
  • TypeScript is portable.


About Typescript Training Course 

 To start: This Typescript training course looks at how TypeScript and React can be used for creating single page applications in JavaScript and HTML. We also have a brief look at Angular and Vue.js. By the end of this course participants will be able to build applications of various complexity with React while adhering to best practices.

Next level: This Typescript Training Course assumes delegates already have a good working knowledge of Javascript and that they also have some exposure to Typescript.

We aim to recap on the basics and move on to cover best practice in using Typescript on a day-to-day basis. TypeScript is JavaScript plus optional strong typing. This course treats TypeScript as it was meant to be treated, as a JavaScript augmentation, rather than an attempt to fix a broken language. We will look at practical migration pathways, and understand how you can use it to increase your velocity in complex projects, without abandoning the core principles that make JavaScript great. If required, we will cover Object-Oriented and Functional topics and will see how TypeScript can help us be faster, more productive, and more accurate in a variety of code forms. This is a practical course and we will be writing code throughout. Taught segments will be interspersed with freeform exercises and Q&A.


Typescript FAQs:

Why is TypeScript so popular?

TypeScript was designed for large web application projects, and it's indeed a good pick. Thanks to types, developers have a much easier time coding the app. The process is much more predictable too. Teams can also use new JavaScript features even if the app needs to support older browsers or Node.

Is TypeScript same as JavaScript?

TypeScript is known as an Object-oriented programming language whereas JavaScript is a scripting language. TypeScript has a feature known as Static typing but JavaScript does not support this feature. TypeScript supports Interfaces but JavaScript does not.

What kind of language is TypeScript?


TypeScript is JavaScript with syntax for types. TypeScript is a strongly typed programming language that builds on JavaScript, giving you better tooling at any scale.

Where is TypeScript used?

TypeScript may be used to develop JavaScript applications for both client-side and server-side execution (as with Node. js or Deno). There are multiple options available for transcompilation. Either the default TypeScript Checker can be used, or the Babel compiler can be invoked to convert TypeScript to JavaScript.

What is the purpose of TypeScript?

TypeScript is a superset of the JavaScript language that has a single open-source compiler and is developed mainly by a single vendor: Microsoft. The goal of TypeScript is to help catch mistakes early through a type system and to make JavaScript development more efficient.

Should I learn TypeScript 2022?

Should You Learn TypeScript or JavaScript in 2022. TypeScript is getting more and more popular, and it's worth learning no matter if you already have experience with other programming languages or just getting into programming. However, you can't learn TypeScript without learning JavaScript
