Language Spotlight: JavaScript

There are over 500 programming languages in the world, and all of them have their own use, application, and value. One that gets tossed around most often as the number one language to learn is JavaScript. It's the oldest programming language around – circa 1995 – and people use it every day.

So... what IS JavaScript?

The complicated version: JavaScript is an object oriented, multi-paradigm, prototype-based language with first-class functions.

The simple version: JavaScript is a scripting language for computers. You’ll see it most often in web browsers. It is used to make web pages responsive and interactive.

JavaScript contains a library of objects and language elements. You connect the objects by using the language elements.

For example: You can use JavaScript to connect back-end functions to viewer-facing functions, such as uploading a document to a website so it can be viewed. You can also use Javascript to connect viewer-facing functions to user-facing functions, such as creating a button that a user clicks to download that same document. This is often called “client-side JavaScript”. Full-Stack Javascript means you incorporate both sides of the language - both the front-end and the back-end.

JavaScript Hello World


Are JavaScript and Java the same?

Not at all. They’re completely different. Java is class-based rather than object-oriented. The two languages can be integrated seamlessly, and they often exist together in applications.

What can you make with Javascript?

Everything from webpages to quizzes to web applications. Some common JavaScript functions include automatically changing a formatted date (you’ll see this in forums, calendars, and blog posts), generating pop-up windows, changing the appearance of an item when you roll over it with your mouse, and formatting drop down-menus.

Who Uses Javascript?

Facebook, Google, Reddit, etc... If you’re interacting with a website, it’s using JavaScript. When you submit a form or download a resource from the internet, the webpage is using back-end JavaScript to transform the data.


This is an easy question to answer. All you need to learn JavaScript is a web browser and a program you can write code in (Notepad works!)


The best way to be taught JavaScript is through an accelerated learning program. There, you’ll be immersed in a quick education that prepares you to get a career as a developer.


When you attend a coding bootcamp program, some (or all) of the curriculum will revolve around the JavaScript language. Some programs include JavaScript amongst several other languages (such as Java, Ruby, or C#) - and other programs focus on JavaScript for the entire length of the course.

So you're probably asking yourself: Which program is right for me?

Answer: It all depends!

Look at geography: No matter where you are in the country, you can benefit from an immersive bootcamp education through an online program. There are in-person programs in almost every state. View our list of bootcamps by location to see if there's one near your doorstep!

Look at culture: Just as you'd be hesitant to attend a college without touring the campus - you need to visit your bootcamp space before committing to it (even if it's through a virtual info session).

Look at outcomes: Ask the school if they have reported their student outcomes. You wouldn't want to spend 12 weeks in a program that won't prepare you for your future. The great thing about Skills Fund: We've done this for you. All of our partners have been through our vetting process to make sure they're worthy of your time and money.
