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

Basically, a function is a special type of object in JavaScript. And in JavaScript, in array you can store anything (not necessarily of the same type). So going by this, yes!, you can store a function, object, and primitive values in an array in JavaScript:

var arr = ["Hello", true, false, 1, {name: "Arshad"}, function(){}]

And you can mix the object and function to make the named function like:

{ callBythisname: function(){ .... }}

You can store this object in an array as well:

var arr = [{ callBythisname: function(){ .... }}];

If you want to call it, call like:

arr[0].callBythisname();
