It's growing faster than any other programming language and big companies like Netflix use it.
What is JavaScript?
JavaScript is a programming language that is used to create interactive effects within web browsers. It is

ECMAScript, but there are other implementations as well.
How Does JavaScript Work in a Browser?
JavaScript runs in the browser's JavaScript engine, which interprets the code and executes it. JavaScript
code can be written directly in the HTML file or in a separate .js file and linked to the HTML file using the
<script> tag.
Features of JavaScript
, Object-oriented programming
Functional programming
Dynamic typing
Closures
Asynchronous programming
These features make JavaScript unique and different from other programming languages.
Getting a Job as a JavaScript Developer
JavaScript developers in the US earn an average of $72,000 a year. You can work as a frontend
developer, backend developer, or full stack developer who knows both the front end and back end.
PayPal and Walmart build entire applications around JavaScript, so there are plenty of opportunities for
JavaScript developers.
If you want to learn JavaScript, there are many resources available online. Check out sites like JavaScript
as a Service and JS as a Side to learn more.
What Can You Do with JavaScript?
JavaScript was originally designed to run only in browsers, but now it can be used to build full-blown
web or mobile apps, real-time networking applications like chats and video streaming services,
command-line tools, and even games. Large companies like Facebook and Google use the language to
build interactive web pages and mobile apps. It has many new features including the ability to run
multiple languages at the same time and create web apps that can run in multiple languages.
JavaScript was created by the group ACMA to standardize the language and is now used by many
companies. Java 2.0, which will be released in September 2015, will include a number of new features
that will allow developers to use it to build mobile apps and web applications. The first version of Java
was released in Java 1.0 in 1995. The second version, Java 3.0, came out in September 2014, and it
comes with a number of new features such as the ability to run multiple languages at once and to use
multiple operators at once. The third version will include the ability to use multiple languages in a single
language at once such as Java 3, C, C++, and Objective-C. The fourth version will also include the
capability to use a range of different languages at one time such as Python, Ruby, and Java.
