I have noticed that data structures are foreign to many less experienced developers with a computer science education. That blows my mind, but then I am self taught. For example consider the following: var1[var2[index][index1]][0] It’s just a combination arrays and objects, but may as well be its own language. The practical problem then is that many developers cannot navigate larger structures that come over a network, cannot recursively walk a file system, cannot traverse a DOM, and cannot do so much more. To me, the person without the computer science education, it looks like their education was a waste of time and money. Understanding data structures is among the most important of all skills in programming.
