JavaScript Chose Violence

10 months ago

JavaScript was created in 10 days and has some quirks.
Date type in JS subtracts 1900 from years, making historical dates incorrect.
Months in JS are zero-based, unlike most numbering systems.
Floating-point arithmetic in JS can lead to precision errors (e.g., 0.1 + 0.2 ≠ 0.3).
Equality in JS can be tricky; always use triple equals (===).
NaN is NaN in JS, but Number.isNaN() is the correct way to check.
parseInt() should include a radix parameter to avoid octal parsing issues.
Avoid eval() due to security risks and poor practice.
JS classes are syntactic sugar and don't fully support OOP.
finally block overrides try block return values, unlike other languages.
Math.min() and Math.max() behave unexpectedly without arguments.
Primitives like numbers can't have methods called on them directly.
Arrays in JS can have non-index properties, acting like hidden rooms.
Despite its flaws, JS has improved and is widely used with tools like TypeScript.
