Throughout this book, we have explored a lot of topics related to JavaScript. You learned how to play with console; solve problems with JavaScript, HTML tags, CSS properties, and control statement; use jQuery; draw with canvas; build projects; and so on. However, have you ever thought about the opportunities that you got by reading the book and learning JavaScript?
Well, in this chapter, we are going to see why learning JavaScript is important and what are the fields of JavaScript.
JavaScript is the easiest language to start learning. It does not need any software to run. A modern browser and notepad are enough to start coding in JavaScript. JavaScript has some of the best online learning materials.
Websites such as Codecademy (https://www.codecademy.com), Code School (https://www.codeschool.com), CodePen (http://codepen.io), JS Bin (https://jsbin.com), and JSFiddle (https://jsfiddle.net) will help you learn JavaScript in short time.
JavaScript is the only language that runs in almost every browser; even in smartphone browsers. As the web is everywhere, JavaScript is also everywhere.
If you enjoy programming and want to build your career with programming, JavaScript is one of the best languages for this. I can say it would be difficult to make better choice than JavaScript. If you look at some of the trends in web development, you will see that real-time websites are like desktop applications. Heavy user interactions on websites such as dragging and dropping, audio and video interactions, and visualization of data are common nowadays. All of these are mostly done using JavaScript. Without JavaScript, we would not get the cool web applications (Google Map, Google Earth, Gmail, Facebook, and so on). JavaScript has made everything possible. No other language is as strong as JavaScript when you want to build web applications. The present world is web-based and web is powered by JavaScript in order to make it beautiful, dynamic, and secure. Therefore, choosing JavaScript with HTML and CSS as your future profession will be one of the best decisions in your life. The developers are known as frontend or full-stack developers.
