Despite massive improvements in JIT compilers and engines like V8, JavaScript still carries fundamental limitations dynamic typing, garbage collection overhead, and runtime interpretation costs. This becomes painfully…

Introduction: Why Memory Has Become the Real Bottleneck For decades, the performance of computers improved mainly by making processors faster. Today, that approach no longer works on its own. CPUs, GPUs, and AI accelerators have become extremely powerful, but they are increasingly forced to wait for data. The real problem is memory. Traditional memory…

But this sense of autonomy is an illusion. Beneath the surface, a far more powerful entity dictates the true order of reality: the scheduler. The Illusion of…
