In the intricate realm of web applications, memory efficiency often hides behind the mask of the garbage collector. While this automated janitor is heralded for its ability to clean up unused memory, its efficacy is frequently overestimated. The difference between the perceived efficiency and the real-world scenario can be exemplified by the Garbage Collector Myth.
"The inefficiencies in our code often mirror the inefficiencies in our teams."
Theorem: The Garbage Collector Myth
Given a web application, the percentage reduction in memory usage after invoking the garbage collector (typically seen during a memory snapshot) mirrors the percentage of non-contributing or under-performing employees in large corporations, particularly those behind such applications.
Evidence:
Discrepancy in Memory Use: When examining the memory footprint of a running web application in a JavaScript engine versus the size after a memory snapshot (which calls the garbage collector), a stark difference is often observed. This snapshot can, at times, show a reduction of up to 400% or more.
Examples in Practice: Notable platforms like Instagram and various other large-scale web services demonstrate properties indicative of non-optimized memory utilization. Often, these applications, much like bloated corporations, contain "dirty" logical instructions that are far from clean, elegant, or RAM-friendly.
Inefficiencies in Code vs. Inefficiencies in Corporations: The amount of unused JavaScript objects in the HEAP, which the garbage collector deems non-essential, can be seen as a metaphor for non-contributing employees in a corporate setting. Just as the garbage collector identifies and removes unused objects to optimize the application, corporations often recognize and (unfortunately) have to address under performing employees for optimal productivity.
Discussion:
The inability of developers to programmatically call the garbage collector and rely on its clean-up is reminiscent of the larger bureaucratic structures where manual interventions are challenging. As a result, developers, like managers, must think differently and optimize at the source.
The Garbage Collector Myth speaks to a greater irony. Web applications, which are developed by teams within corporations, reflect the inefficiencies inherent in those very corporations. The non-essential objects cluttering the HEAP are analogous to employees whose roles have become obsolete or redundant in the fast-evolving corporate world.
Conclusion:
This theorem, while humorous in its parallelism, underscores two critical messages:
Web Application Development: Developers must be vigilant and proactive in optimizing memory usage from the onset, rather than relying solely on garbage collectors. This will result in cleaner, faster, and more efficient applications that provide enhanced user experiences.
Corporate Structure: Modern corporations, especially tech giants, should constantly evaluate and optimize their structures, ensuring that every team member contributes positively to the organization's overarching goals.
In essence, both the world of web development and corporate structures could benefit from regular introspection, efficient design, and proactive optimization. 😊

It's likely that those applications exhibiting large amounts of unused memory are using immutability and functional programming concepts in their code - these generate vast amounts of garbage as objects are constantly copied. It's one of the costs of using such patterns but generally doesn't cause much of an impact for the user.
I find it quite disgusting talking about human beings as inefficiency that should be optimised away. This article also gives no guidance as to how one should go about improving performance of a web app.
