Knowing how to code has become a life skill, but it is also a skill in demand. Startups need talent, and are willing to pay top dollar for it — the average salary of a US programmer is now over $100,000. Likewise, if you’re thinking of going it alone in the world of business, being able to build your own product is invaluable.

To help get you started, here’s a list of great e-learning courses (and bundles of courses) at major discounts.
