javascript

Functions in javascript can be named or anonymous. They have access to local variables that are in the scope of their parent functions.

    function fun2(){
        var output = ""
        if(typeof myGlobal != "undefined"){
            output += "myGlobal: " + myGlobal;
        }
        if(typeof oopsGlobal != "undefined"){
            output += " oopsGlobal: " + oopsGlobal;
        }
        console.log(output)
    }

These are defined with the following syntax:

var person = {
    firstName : "Jack",
    lastName : "Smith",
    age : 19,
    employed : true
}
