WE LAUNCH IN 45 MINUTES TeachYourselfCrypto course verified certificates and private community Add Crypto to your resume Companies are looking for crypto-literate professionals to join their teams. Most of these companies offer pay in 6 figures, with remote-WFH options available, consistent with the crypto culture. Even traditional companies are looking for individuals who can spearhead blockchain adoption in their company. You don't need to be a developer for this, but you do need to know how to use the tools. Getting certified by TeachYourselfCrypto allows you to showcase your knowledge on a cutting edge, fast paced topic, while communicating to prospective employers that you have the skills, foresight and competence to adapt to a fast changing environment. The community is a place to learn more about crypto, connect with other members, and communicate with other crypto-literate people (i.e. not like twitter where everyone is an expert on everything.) If you buy before launch (use code "preorder"), you get 50% off on all certificates and lifetime access to the private community. We launch in 45 minutes! https://lifemathmoney.gumroad.com/l/cert

"Part of the inhumanity of the computer is that, once it is competently programmed and working smoothly, it is completely honest." - Isaac Asimov

In JavaScript, a function always returns a value. If the return value is not specified, then it returns undefined.

"Test doubles are objects that replace real dependencies to enable automated testing. They are the automated testing equivalent of movie stunt people: they take the place of the original since having the real one is expensive or impractical." Excellent analogy by @venkat_s

First, make it work. Then, make it fast.

"There are no significant bugs in our released software that any significant number of users want fixed." - Bill Gates

In theory, theory and practice are the same. In practice, they're not.

Inside every complex program is a simple program trying to get out

You can get all the certificates and *lifetime* access to the private community for a 50% off before we launch tomorrow at 7pm India time. Go here: https://lifemathmoney.gumroad.com/l/cert

If the code and the comments disagree, they are both probably wrong

"Program testing can be a very effective way to show the presence of bugs, but is hopelessly inadequate for showing their absence." - Edsger Dijkstra

There are no "simple" bugs.

"The only constructive theory connecting neuroscience and psychology will arise from the study of software." - Alan J. Perlis

"Every program has (at least) two purposes: the one for which it was written, and another for which it wasn't." - Alan J. Perlis

I've yet to see a UML diagram in a professional environment.

Theory is when you know something, but it doesn't work Practice is when something works, but you don't know why Programmers combine theory and practice Nothing works and they don't know why

Check for if (-1 == x) instead of if (x == -1) to avoid bugs like if(x = -1)
