Introduction
Threading is a fundamental concept in computer programming where multiple instructions are interleaved to enable parallelism and improve performance. It's crucial for tasks like multi-threading, data processing, and image processing.
Key Concepts
- Threads: Lightweight units of execution within a process.
- Synchronization: Mechanisms to coordinate access to shared resources (mutexes, semaphores).
- Concurrency: The ability to execute multiple tasks seemingly at the same time.
- Benefits: Improved throughput, responsiveness, and resource utilization.
Example Code
Let's create a simple example using a worker thread:
function worker(id) {
print("Worker " + id + " started");
for (let i = 0; i < 3; i++) {
print("Processing iteration: " + i);
}
}
worker(1);
worker(2);
worker(3);
