JavaScript’s quirks and evolving standards

JavaScript has historically been known for its quirks and idiosyncrasies. These unusual characteristics often arise from its evolution as a language and the need to maintain backward compatibility, among other factors. For instance, a notable quirk in JavaScript is type coercion: JavaScript tries to be forgiving with data types, which can lead to unexpected behavior when different types are mixed.

It’s important for developers to be aware of these aspects of JavaScript in order to write more robust and predictable code. Fortunately, the ECMAScript standard, which defines JavaScript, is evolving to address many of these issues and introducing more predictable behavior and additional features to the language.
