Why You Might Want to Start Speaking in Code

Want a high-paying job? It might be time to learn to write code, and it's not as hard as it sounds.

Computer programming jobs are growing at twice the national average, but not enough Americans are learning to code. By 2020 it's estimated that there will be 1 million more computer sciences jobs than graduates, according to Code.org, a nonprofit foundation dedicated to expanding computer programming education.

That's where Codecademy comes in.

"What we want in the 21st century is for programming to become just as important as reading and writing, and for people to think in algorithms," founder Zach Sims told CNBC's "Squawk on the Street" on Friday.

With the proliferation of smartphone apps and other software applications, every job needs a little bit of programming and computer knowledge.

Learning to code isn't as difficult as it sounds, Sims said.

"You work on projects as you go through," Sims said. "So you build websites, build games and you never really graduate because there's always something new to learn."

The site is currently free and helps people learn programming languages like JavaScript, HTML and CSS interactively.

And learning to code can lead to career opportunities.

"We've seen whole businesses created by people that learned programming on Codecademy, then sell apps on the App store and make a living," he said.
