What's The Most Important Language You'll Ever Learn?

What is the most important language you'll ever learn? JavaScript. And, really, there's never been a better time to learn to code. There's a large demand for coders and you can quickly become a highly paid front-end web developer – even if you have no coding experience. There are many programming languages out there, but the most commonly used programming language on Earth is JavaScript.

What is JavaScript?

Most websites contain code from three different languages – HTML, CSS, and JavaScript – and it's important that you understand what each of them does. HTML (Hypertext Markup Language) lets you put text on a webpage, but it has very few formatting options. Think of it as a plain webpage like Craigslist where everything looks the same. CSS (Cascading Style Sheets) lets you alter how HTML elements look with tools like fonts and colors so everything looks nice and pretty. Think of it as a barebones personal website that just has text and graphics like the rockin' GeoCities sites of yore. JavaScript lets you have sophisticated programming that does everything else that you associate with a modern webpage.

For example, consider Twitter. When you scroll to the bottom of the page and it automatically refreshes more tweets, that's JavaScript. When you click on a tweet and it expands, that's JavaScript. When you click on the New Tweet button, compose a tweet, and press Tweet, that's all JavaScript too. In essence, HTML and CSS are like a printed newspaper full of colorful words and images, but JavaScript is like an iPad – it's an interactive piece of technology.

What Else Can JavaScript Do?

As you probably gathered from the Twitter example, JavaScript is an extremely versatile language that can be used for a variety of tasks. It allows you to store information inside a variable. For example, if you order food from a website, the website can call you "(insert name here)" instead of "customer". JavaScript also lets you run an operation on a piece of text. For example, once you've placed your food order, the website can say "Thank you (insert name here)". JavaScript can also run code in response to a certain action that a user takes on a webpage. For example, after you've clicked "Place Order", the website can take your money and send the food order to the kitchen staff.

In addition to building your own functionality, you can also use APIs (Application Programming Interfaces) to add functionality from third-party apps to your JavaScript code. For example, you can use the Twitter API to embed your most recent tweets on your website or you can use the Google Maps API to link to a map of the restaurant so you can pick up your food.

Where else can I use JavaScript?

One of the strengths of JavaScript is that it can be used for many different kinds of code. Much like HTML and CSS, JavaScript can run client-side code – code run on a user's computer when a user views a webpage. But unlike HTML and CSS, JavaScript can also run server-side code – code that runs behind the scenes on a server in order to do more complex tasks like retrieving data from a database.

JavaScript can also be used to program apps for smartphones and tablets. It can even be used to program responsive websites that automatically resize themselves to fit on any screen – regardless of size.

Whether you want to code front-end, back-end, client-side, or server-side, you'll find that JavaScript is one of the most useful and versatile programming languages.

How do I learn it?

You can easily learn how to program in JavaScript with the Essential JavaScript Coding Bundle. This bundle includes 15 courses that will teach you everything you need to know to become a highly sought-after JavaScript developer.

You'll start by learning the basics of JavaScript so you can build websites with popular frameworks like Bootstrap and Angular JS. Then, you'll explore key modern tools in the JavaScript ecosystem including JavaScript libraries like D3.js. Finally, you'll move on to more advanced topics such as functional programming, data visualization, and mobile application development. By the time you're finished, you'll have an impressive portfolio and will be an expert in all things JavaScript.

The Essential JavaScript Coding Bundle contains $1,080 worth of content, but you can get it today for just $29.
