Can I store JavaScript functions in arrays?

Question

How can I store functions in an array with named properties, so I can call like

FunctionArray["DoThis"]

or even

Function         


        

Answer 1

Here is an array that contains various data types, including a function.

Although there is an object in this example, the function is not within the object.

If you replace this object with a string, the function will still work as planned.

I can call the function from within or without the array.

myArray = [
        1,
        true,
        "String",
        {
            name: "trey",
            age: 43,
        },
        [1,2,3,4],
        myFunction = function(){
            console.log("What\'s up!");
        },
        myArray[5](),
    ];
    console.log(myArray);
    myArray[5]();

Here is the output:

What's up!
[ 1, true, 'String', { name: 'trey', age: 43 }, [ 1, 2, 3, 4 ], [Function], undefined ]
What's up!
