HackerRank is a place where programmers from all over the world come together to solve problems in a wide range of Computer Science domains such as algorithms, machine learning, or artificial intelligence, as well as to practice different programming paradigms like functional programming.

HackerRank is very good for beginners so even if you want to print your first program “Hello World!” then definitely HackerRank gives this opportunity to you. It has a pretty good UI with boilerplate code pre-written that helps beginners to start competitive coding.

The HackerRank Jobs app/Web site lets candidates browse job openings at nearly 40 participating companies, such as VMware, Box, Visa, Uber, and Quora. Candidates can specify job roles in their browsing, such as back-end, front-end, mobile, or DevOps developer positions, along with the location.

Explore and attempt front-end coding challenges on Codier.

Challenges on Codier can be anything that the challenger wants them to be; if it’s a Pure CSS Checkbox challenge, the user that creates the challenge can specify that in the rules of the challenge. They can also add a template to get creators started – templates can be the basic HTML structure for a challenge or even just a framework like React.

Creations on Codier can be built through a combination of HTML, CSS, and JavaScript within the editor. Users can alternatively use preprocessors to write their creations, and even include external resources.

Codier is a lot more than just a platform for people to find challenges. We believe it is a great place for learning, and also as a source of inspiration.
