Class Fields Initialize in ORDER?!
Class fields initialize SEQUENTIALLY! Field a tries to access field b BEFORE b is initialized. This creates undefined references that will confuse you!

Function.length Counts Parameters WRONG?!
Function.length LIES! It counts parameters, but stops at default values. Rest parameters don't count. This property is DECEPTIVE!

Math.max() With No Arguments?!
Calling Math.max() with nothing returns something you'd NEVER expect! This will break your logic! Watch the chaos!

[1,2,3] == [1,2,3] Is FALSE?!
JavaScript array comparison is broken! Two identical arrays are NOT equal. This is why your code fails! Watch the reveal!

Object Keys Order Is INSANE!
JavaScript object key ordering will break your brain! Number keys vs string keys get sorted differently. This breaks everything! Watch!

Symbol.iterator Creates INFINITE Sequence?!
Custom iterators can generate INFINITE sequences! This object never ends, but spread operator can slice it. This is how generators break the rules of finite data!

Destructuring Defaults Are TRICKY?!
Destructuring defaults have LAYERS! Nested defaults work differently than you think. undefined triggers defaults, but missing properties don't! This is confusing!

Modifying Array.prototype Affects ALL Arrays?!
Array.prototype is GLOBAL! Adding methods affects EVERY array in your code. This global pollution will break other code. This is why you never modify prototypes!

Getter That MODIFIES Itself When Called?!
This getter is ALIVE! Every time you access it, it CHANGES its own behavior. First call returns one value, second call returns something completely different. This self-modifying code will break your logic!

Static Block Runs at Class Definition?!
Static blocks are SECRET! They run when the class is defined, not when instantiated. This is how you initialize static properties with complex logic!
