Welcome to the Javascript-closures-fact-three- wiki!

Closures are not supported in all programming languages, but they are in Javascript. It seems to understand them, it is necessary to look at three facts about closures.

This is the third one and the others can be found here:

• Fact One
• Fact Two

Fact three says that a variable which is defined in an outer function can be updated. For example

function anyFunction()
{
    //Similar to a member variable
    var varOutside = undefined;
    
    return {
        //Similar to methods
        setValue: function(newValue)
        {
            varOutside = newValue;
        },
        getValue: function()
        {
            return varOutside;
        }
    };
}

var myObject = anyFunction();
myObject.setValue(1000);
console.log( myObject.getValue() );//Outputs 1000

STILL IN WORK(for longer)!!
