В кластер входят документы о вычислительной эффективности и производительности JavaScript и веб-технологий в сравнении с аппаратным обеспечением или системными API.
Общие признаки: эффективность JavaScript, ресурсозатратность веб-интерфейсов, сравнение с системными API, влияние DOM на скорость работы
Группа выше: Рендеринг и вычисления в браузере
Смысл: The author is questioning why JavaScript is so computationally expensive and inefficient compared to the available hardware power of modern CPUs, especially for simple UI effects.
An individual asks why JavaScript is so resource-intensive and why small performance gains in browsers are marketed as major breakthroughs.
Смысл: The main idea is that JavaScript is an incredibly fast interpreted language due to intense industry competition, and the common perception of it being 'slow' is actually a result of the inefficient nature of the DOM, not the language engine itself.
JavaScript's reputation for being slow is a misconception caused by the inefficient DOM, whereas its actual execution speed is highly competitive, even rivaling C++ in specific benchmarks.
Смысл: The main idea is that modern web technologies (HTML/CSS/JS) are absurdly inefficient and imprecise compared to legacy OS graphics APIs, requiring far more hardware power to achieve simpler results.
The author argues that modern web development is a performance regression, as 20-year-old systems handled complex graphics more efficiently than today's browser-based stacks.
