Learn the basics of coding on your phone with Google’s new Grasshopper app

Google has an answer for those who say, “I wish I learned how to code.” From Area 120, Google’s experimental workshop, comes Grasshopper, a free app for Android and iOS that uses our love for games and puzzles to teach us JavaScript. With engaging guides and achievement points driving up you along, you will get a basic understanding of how to write JavaScript and other coding concepts.

“Grasshopper is the best way to start your coding adventure with fun, quick games on your phone that teach you to write real JavaScript,” Google wrote in their iOS app store preview. The app is also available in the Google Play Store.

“Move through progressively challenging levels as you develop your abilities, then graduate with fundamental programming skills for your next step as a coder.”

Google’s internal incubator Area 120 is named after the “20 percent” time employees are allowed to work on anything. Since its creation in 2016, Google workshop has created apps that let you watch YouTube videos together with friends, a Smart Reply feature for notifications from any Google apps, and a recently announced Shortwave app that will help users discover and consume spoken-word audio in new ways, according to 9to5Google.

“Excellent really good way for a beginner to learner! If you aren’t completely new to code it’s verrry slow but I didn’t mind refreshing the basics because it’s such a cute app!” said Funmilayo Aiyenuro in her five-star rating of the app.

In his review, Eric Venable wrote that it was “very visual so it is great for visual and hands on learning.”

“Hoping it gets more challenging so I can see what I have actually learned and remembered. Also would like to be given a problem to solve on my own instead of being told step by step exactly what to do,” he added.

There are dozens of great ways to learn how to code through apps and websites like Khan Academy and Codecademy, but the Grasshopper app is ideal for those looking to test the coding waters before diving in fully. The use of games, achievement points, and puzzles should help beginners get a base-level understanding of JavaScript so they can move on to more rigorous courses.

According to TechRepublic, the app goes over calling functions, variables, strings, loops, arrays, conditionals, operators, and objects. Through Grasshoper you’ll be able to define functions, make callback functions, create animations and draw shapes using the D3 library. It is still unclear if they will eventually add other coding languages.
