Web APIs (navigator, geolocation, history)

navigator.hardwareConcurrency reports available logical processors: 1) It returns the number of logical processor cores available to the browser, 2) This helps web applications adapt their parallelization strategy to the device's capabilities, 3) For example, a web worker pool might be sized based on this value, 4) The reported value may be lower than the actual number of cores due to browser restrictions or user agent policies, 5) It provides a hint for compute-intensive applications like image processing, simulations, or encoding, 6) It's particularly valuable for progressive enhancement of computationally intensive features, 7) The value typically ranges from 1 on low-end devices to 8, 16, or more on high-end systems, 8) Unlike more detailed system information, this property strikes a balance between usefulness and privacy preservation.
