package mypackage var PublicVar string = "Hello, dear reader!" //Calculates the factorial of given number recursively! func Factorial(x uint) uint { if x == 0 { return 1 } return x * Factorial(x-1) }

Now you can start writing your own go code with auto-completion using Atom and Gulp: package main import ( "fmt" "mypackage" ) func main() { println("4! = ", mypackage.Factorial(4)) }

function myFunction(x, y, z) { } var args = [0, 1, 2]; myFunction(...args); The spread syntax allows an expression to be expanded in places where multiple arguments (for function calls) or multiple elements (for array literals) or multiple variables are expected. Just like the rest parameters s...

try...catch block is for handling exceptions, remember exception means the thrown error not the error. try { var a = 1; b++; //this will cause an error because be is undefined console.log(b); //this line will not be executed } catch (error) { console.log(error); //here we handl...
