Objective-C:

    - (return_type) method_name:( argumentType1 )argumentName1   
    joiningArgument2:( argumentType2 )argumentName2 ...  
    joiningArgumentn:( argumentTypen )argumentNamen  
    {  
       body of the function  
    }

Swift:

    func funcname(Parameters) -> returntype {  
       Statement1  
       Statement2  
       ---  
       Statement N  
       return parameters  
    }

Javascript:

    function functionname(parameter-list)  
    {  
        statements  
    }

I know people downvoted op, but when I first learned it, reading Objective-C made me angry. The second two examples are much closer in syntax and style and require much less context switching.

And it wasn't mentioned, but the if let myVar = optionalVar { ... } is a godsend for writing maintainable, crash-free code.
