Chapter 38- Conceptual Aside (Arrays - Collections of Anything)

Notes​

Array can be declared as
var arr = new Array();
var arr = [1,2,3];
JS arrays are dynamically typed


var arr = [
	1,
	false,
	{
	name : ‘Tony',
	address : ‘22 Main st'
},
//it's a function expression not statement inside array declaration
function(name){
	var greeting = "hello";
	console.log(greeting + name);
},
"hello"
];

JS array can hold collections of anything.
Invoking function in an array with param in array
arr[3](arr[2].name);
