Thinking About Your Code: Push vs Pull
summary
Code is cast as producers and consumers and categorized into a four-way chart: push vs pull primitives are functions and iterables (pull), callbacks/promises/observables (push), async iterables (pull then push), and signals (push then pull). A live M&M demo shows back pressure when production outpaces consumption. Examples use observables, async/await, async iterators and a real Netflix dashboard handling hundreds of millions of devices across thousands of servers and over half North America bandwidth.
