JavaScript Tutorial for Beginners
Welcome to the JavaScript world! You've come to the right place if you want to explore the fascinating and dynamic world of web development. Powerful programming languages like JavaScript are used to build interactive and captivating web pages and applications.
JavaScript has grown to be a crucial component of the modern web developer's toolkit, used for everything from adding straightforward animations to building intricate user interfaces.
Therefore, I will attempt to cover all the necessary JavaScript topics for beginners in this tutorial. But before we begin, I'm willing to discuss some interesting and informative details about the "JavaScript" programming language.
What is JavaScript?
JavaScript is a dynamic, high-level, interpreted language that is simple to use. It supports procedural, functional, and object-oriented programming. JavaScript can be used to make sophisticated web applications or just simple interactive elements for web pages.
Popular programming language JavaScript is frequently used in web development. It runs on the client's computer rather than the web server because it is a client-side scripting language.
Who created JavaScript?
Brendan Eich created JavaScript in 1995 while employed at Netscape Communications Corporation. It was initially developed to add interactivity and increase the dynamic nature of web pages.
What is the official website of JavaScript?
The JavaScript programming language's official website is https://developer.mozilla.org/en-US/docs/Web/JavaScript. Mozilla, the creators of the Firefox web browser, maintains this website.
What is the filename extension of JavaScript?
".js" is the most typical file extension for JavaScript files. It is advised to end a JavaScript file's filename with ".js" when creating one. Other developers will find it simpler to understand that the file contains JavaScript code as a result.
There are other extensions associated with JavaScript like ".mjs" (ECMAScript module system), ".jsx" (React components), etc.
What language influenced JavaScript?
The JavaScript programming language was influenced by, but is not limited to, the following languages:
- Java
- Scheme
- AWK
Languages influenced by JavaScript
The JavaScript programming language has influenced the following languages, among others:
- ActionScript
- CoffeeScript
- Dart
- TypeScript
What are the reasons to learn JavaScript?
One might decide to learn JavaScript for a variety of reasons, but some of the most prevalent ones are as follows:
- Easy to Learn
- Popularity
- High Demand
- Job opportunities and high salaries
- Object-oriented programming
- Community and support
- Versatility
I mentioned "versatility" as one of the reasons to learn JavaScript because it can be used to develop both front-end and back-end applications. We can use a JavaScript framework such as "Node.js" to implement JavaScript as a back-end language.
What is JavaScript used for?
The JavaScript programming language allows us to do a variety of things, the most common of which are as follows:
- Web Development
- Mobile App Development
- Game Development
- Server-Side Development
- Desktop Application Development
Famous applications using JavaScript
Numerous applications utilize JavaScript, but here are some of the most well-known:
- Google Maps
- Gmail
- Google Drive
- Netflix
- Amazon
- Airbnb
- Spotify
Is JavaScript a platform-independent language?
JavaScript is platform-independent, which implies that you only need to write the script once and can run it on any platform or browser without affecting the script's output.
Advantages of JavaScript
- Since it is not overly difficult to pick up, JavaScript is an excellent language for those just starting out.
- JavaScript is versatile enough to be utilized for a wide range of purposes, such as the development of web applications, mobile applications, server-side applications, video game applications, and more.
- Code written in JavaScript can be executed on a variety of platforms, such as web browsers, mobile devices, and desktop computers.
- Developers have the ability to create user interfaces that are dynamic, interactive, and engaging thanks to JavaScript.
- Because there is a large community of developers working on JavaScript, it is simple to locate assistance, resources, and libraries.
Disadvantages of JavaScript
- The performance of JavaScript can be impacted by things like browser, device, and network speed, which can lead to slower page loads.
- Maintaining JavaScript code can be difficult, particularly as applications become more complex.
Audience
This tutorial is intended for JavaScript enthusiasts who are new to the language and want to learn it from the ground up, as we have included as much code as is necessary in each post of this JavaScript tutorial series.
As a result, you can easily follow this JavaScript tutorial series to learn JavaScript.
Prerequisites
Before you begin learning JavaScript, you should be familiar with HTML because JavaScript is a language used to trigger HTML elements to perform user-defined actions.
If you already know HTML and how to code, learning JavaScript will be a breeze. However, I explained each post in this JavaScript tutorial series with examples whenever possible. So don't be concerned if you don't know how to program 😍.
