Fred Brooks, in his all-time best-selling computer science text, The Mythical Man-Month says:
Representation is the essence of computer programming. … Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won’t usually need your flowcharts; they’ll be obvious.
Tools like LSP have made it possible to navigate code using static-types so much easier than they were even a just a decade or so ago. Representation with types or at the very least, hierarchical schemas, is essential for any complex piece of code.
