I suspect Toxico is speaking about a particular challenge that has
come up with educators teaching particularly OO languages as first
languages. Specifically, because of the strong encapsulation and
data hiding techniques present in these languages, a wide ecosystem
of reusable class libraries has surrounded them - to the point where
programming in these languages is often seen as an integration
effort - trying to integrate a series of class libraries. As a
result, a certain segment of the programming community has lost
understanding of huge swaths of the practice - particularly
foundational algorithms - such as searching and sorting algs -
because learning programmers just use rather than implement.<br>
<br>
When you are reusing code (like a sorting or search algorithm, or a
hash tree class in Java), think about whether you understand (at
least in basic terms) how that code is likely implemented. If you
were given the task of implementing a hash table (because
java.util.HashMap was unavailable to you), would you be able to?
Would you know where to start? Would you be able to describe the
performance characteristics of a search, insert or delete using this
structure? These are important questions that you should learn to
answer...<br>
