Learn JavaScript, deeply – Matt Mullenweg

I think Matt meant for PHP developers to learn JavaScript and for us to learn vanilla JavaScript in particular so we could program with it regardless of framework. Learning JavaScript deeply was important because, over the next few years, framework development continued quickly. Every year a different library, framework, or flavor of JS would become popular.
Vanilla JavaScript developed quickly as well with the base language itself gaining new features. Different browsers adopted the new features at different rates, requiring polyfill solutions, requiring compilers and package managers. I honestly don’t know how new developers pick this stuff up. The JavaScript landscape seems very confusing right now. Maybe it’s more confusing for folks like me who have been using JavaScript since 1995.
