I vote for snake cased [Hungarian notation](https://en.wikipedia.org/wiki/Hungarian_notation) for our javascript.

```
function funGlob_MySuperAwesomeFunction () {
    var someClass_myInstance = new SomeClass(), 
          str_anotherVariable  = "test";

    someClass_myInstance.funInst_someOtherSuperCoolFunction();
    str_anotherVariable = someClass_myInstance.funInst_someOtherSuperCoolFunction(anotherVariable);
}
