Programming languages and technologies change at lightspeed, and it’s changing the way companies and developers do business, interact with clients, and stay on the cutting edge.
By 2022, demand for software developers is expected to grow by 20%, compared to just 10.8% growth for other industries.
But while demand is increasing rapidly, some languages and technologies have grown faster than others.
Here are the languages and technologies that have recently been demanded by the highest percentage of Toptal clients:
And here’s a look at the technologies and programming languages that are growing fastest in terms of client demand.

So what does this tell us?

JavaScript continues its astounding growth.
At 31.36% client demand, the world’s most popular programming language continues to be everywhere.
What’s more, JavaScript-based technologies look to be building on the language’s success, with AngularJS and Backbone.js topping the list of most rapidly growing technologies.
At an amazing 541.94% growth in demand over the past year, AngularJS is a must-learn framework for front-end developers looking to stay on the cutting edge.
