A situation has arisen where I am executing multiple (let's say four) AJAX calls using AngularJS http get, and I desire each call to invoke a callback function that increments a counter. This way, I can track when all four threads have finished.
I am worried because JavaScript lacks constructs like Java's "synchronized" or "volatile" keywords, which could potentially result in race conditions where two threads collide while incrementing the counter, causing some increments to be missed.
For instance, if two threads access the counter simultaneously, both may read the same value (e.g., 100). Subsequently, they both increment the counter (to 101), leading to an overlooked count (101 instead of the expected 102).
While JavaScript is typically single-threaded, there are exceptions to consider.
Could this scenario actually occur in the browser? If so, is there a method to prevent it?
