What I don't like in JavaScript

a year ago

JavaScript has a simple design, making it easy to learn.
It features a unified variable model, allowing any type of data to be stored in variables.
Closures are supported out of the box, facilitating complex function behaviors and encapsulation.
Asynchronous design with async/await support enhances coding experience.
Ergonomic syntax, comparable to Python, improves readability and writability.
Monkey patching allows for flexible modifications to built-in functionality.
JavaScript is performant for a dynamically typed language, sometimes rivaling C/C++.
Versatility beyond low-level programming and backward compatibility are key strengths.
Design flaws include type coercion quirks, though avoidable with good practices.
`typeof null` returns 'object' due to historical reasons, causing confusion.
Comparing two NaN values yields false, requiring special handling.
Default `Array.prototype.sort()` sorts lexicographically, not numerically.
Newline sensitivity can lead to unexpected behavior in return statements.
Omitting `var`, `let`, or `const` accidentally declares global variables.
Octal numbers with leading zeros can cause misinterpretation.
Array constructor behavior varies unpredictably with argument count.
