Vim : Moving Through Code

I want to be able to navigate the cursor across functions using Vim. Mainly, I want a command to allow me to go to the next function, like } allows me to go to the next paragraph. I found this:

Go to the end of the开发者_JAVA百科 C++ function in Vim

Unfortunately, it doesn't seem to work fine in JavaScript. Also, I believe it would also not work for Python, as Python don't depend much on { and }.

Any help?

In a Python file I find:

• } will take me to the end of a block,
• ]] will take me to the start of the next function.
• [[ takes me to the start of the current function, or the one above if I keep pressing.

]} didn't seem to work though.
