JavaScript GameDev Tutorial – Code an Animated Physics Game [Full Course]

Web Reference: Novice JavaScript developers need to know that the "not not" operator is using implicitly the original loose comparison method instead of the exact or operators and also the hidden cast operation that is happening behind the scenes and I show it in the example I provide. Related to Is there a "null coalescing" operator in JavaScript? - JavaScript now has a ?? operator which I see in use more frequently.
