Bill Gates was able to get into programming at an early age because the prep school he attended gave students access to a GE mainframe computer. Mark Zuckerberg, meanwhile, had a private programming tutor growing up. And while that early coding education wasn't the only factor that led to those guys becoming incredibly successful developers (and, ya know, billionaires), it certainly didn't hurt either.
The majority of us, however, didn't grow up with this type of exposure to the world of coding. And many of us are still unclear how it all works -- how writing and combining complex strings of words and characters can lead to the creation of web browsers, websites, operating systems, smartphone apps, and more.
The good news: It's never too late to learn. And to help you learn how to code (or to simply help you better understand how coding works), we've put together an exhaustive list of resources. Let's dive in.
17 Resources for Learning How to Code
Online Coding Schools
1) Codeacademy
Now boasting more than 25 million users, Codeacademy is one of the most popular resources for learning how to code on the planet. The online education platform offers interactive coding courses across several different programming languages, including JavaScript, Python, and Ruby. They also have courses that cover markup languages (e.g., HTML) and stylesheet languages (e.g., CSS).
And just to clarify: These aren't lecture-style courses we're talking about here. You actually get to do some hands-on coding and see changes in real-time. Best of all: Codeacademy courses are 100% free.
2) Khan Academy
Another major player in the coding education space is the nonprofit Khan Academy, whose mission is to "provide a free, world-class education for anyone, anywhere." Like Code Academy, Khan Academy offers courses in several different programming languages, which include interactive segments where you get to play around with code.
The one major difference is that Khan Academy courses rely more heavily on video. Founder Salman Khan got the idea for the academy after creating and sharing tutorials on YouTube.
3) Treehouse
Online technology school Treehouse offers coding courses from beginner level to expert. But unlike the first two options on this list, you'll need to fork over some cash before you can start learning. For $25 per month, you can gain access to Treehouse's library of 1,000+ videos and take interactive coding challenges. For $49 per month, you can unlock bonus content and gain the ability to download videos for watching offline.
4) Code School
The aptly named Code School follows a similar model as Treehouse: students watch video tutorials, and then get a chance to put what they've learned into action with interactive coding challenges. For $29 per month, you can get access to Code School's 50+ courses and 200 videos. (There's also a free option, FYI, which gives you access to 10 of their courses.)
5) Code Avengers
Code Avengers is another online coding school, which provides interactive courses on JavaScript, HTML, CSS, and more. While some of the introductory courses are free, you have to pay around $30 a pop to unlock the more advanced ones. (Note: You can save money by buying multiple courses in a bundle.)
6) SkillCrush -- Break Into Tech
With over 4,000+ alumni, Break Into Tech is SkillCrush's most robust, personalized online training program. It gives attendees access to 15 interactive classes in technical skills and career development, regular one-on-one career counseling sessions, and access to a learning community.
7) Bento
Founded by Stack Overflow developer Jon Chan, Bento is free a coding education website that offers two distinct ways to learn. One option is to follow learning tracks, which feature educational content that's been curated by professional programmers. The second option is to look through the Bento Grid (pictured below), which is a meticulously organized collection of the top coding resources on the web.
8) MIT OpenCourseWare
MIT OpenCourseWare is a free online library of course materials from more than 2,200 MIT graduate and undergraduate courses. The idea behind the program, according to MIT School of Engineering Professor Dick K.P. Yue, is simple: "to publish all of our course materials online and make them widely available to everyone."
Each OpenCourseWare course consists of two components: an instruction component (e.g., a lecture or reading list), and a learning activity (e.g., an exam or assignment).
9) Programmr
Describing itself as the "Programmer's Playground," coding platform Programmr takes a more lighthearted approach to teaching people how to code. In addition to offering seven different interactive courses, Programmr lets you hone your skills through taking challenges, signing up for projects, and even entering coding contents where you can win cash prizes.
10) Udacity
Similar in spirit to MIT OpenCourseWare, Udacity got its start in 2011 as a way to make Stanford University computer science courses available for free. Since then, it has evolved into an education platform that offers courses and "nanodegree programs" from educational institutions as well as tech companies like Google, Facebook, and Twitter.
Massive Open Online Courses (MOOCs)
11) Coursera
Coursera is a for-profit, ed-tech company that offers massive open online courses, also known as "MOOCs." MOOCs are courses from universities and other institutions that have been made available online with few (if any) limits on who can participate in them.
With more than 15 million users, Coursera is one of the largest providers of MOOCs in the world, and offers hundreds on programming and related fields. One of their most popular MOOCs at the moment: University of Michigan's "Programming for Everybody (Getting Started with Python)."
12) edX
Like Coursera, edX is a MOOC provider that serves millions of students. Some of their most popular courses (which are starting soon) include IIT Bombay's "Fundamentals of Computer Science" and an HTML5 introduction course that was developed by W3C and Intel.
Unlike Coursera, edX is a nonprofit and it's open source, so anyone can build tools for and contribute features to the edX platform.
13) Udemy
Offering courses like the popular "Complete Java Developer Course," Udemy is another (for-profit) MOOC provider that can help you develop your coding skills. One of the unique features of Udemy is that anyone can sign up to become an instructor and create their own course.
Coding Apps
14) Scratch
While it was designed for kids and teenagers, the educational web app Scratch -- created at the MIT Media Lab -- can be a fun way for adults to learn about the basics of coding. The app lets you program your own games, animations, and interactive stories, and you can share these coded creations with others via Scratch's online community.
15) Hopscotch
The free iPhone and iPad app Hopscotch is another fun option for learning coding basics. With Hopscotch, you can create unique games and share them with others so anyone can play. There are also in-app tutorials that provide line-by-line instructions for creating specific types of games. Hopscotch currently has 4.5 stars in the app store (based on 515 ratings).
16) Codea
Wired once referred to Codea as the "Garageband of Coding." The $14.99 iPad app is like a grown-up version of Hopscotch. Through tapping, dragging, and dropping different elements, you can code up games, simulations, and other visual creations. Codea currently has 4.5 stars in the app store (based on 746 ratings).

17) HTML Hacks for Marketers: Decoded
This site page, which we co-created with Codeacademy, is a great starting point for marketers who want to understand the basics of HTML, a.k.a. "the language of the web." From formatting text, to customizing colors, to creating internal page links, this free resource provides HTML tips and tricks that will definitely come in handy.
