The SpinWaitLock class is a custom implementation of a spin-wait lock mechanism. This class provides a lightweight synchronization primitive that repeatedly checks a condition in a loop until it is met, which can be useful in scenarios where synchronization is required without sleeping the event loop.
Acquire(): Attempts to acquire the lock. If the lock is already held, it will spin in a loop until the lock becomes available.Release(): Releases the lock, allowing other threads to acquire it.
import { SpinWaitLock } from './SpinWaitLock';
const lock = new SpinWaitLock();
async function criticalSection() {
lock.Acquire();
try {
// Critical section code goes here
console.log('Lock acquired, executing critical section');
} finally {
lock.Release();
console.log('Lock released');
}
}
async function main() {
await Promise.all([criticalSection(), criticalSection()]);
}
main()
.catch(console.error);
