Learn to write and process multidimensional arrays using JavaScript. They are called Multidimensional because they contain one or more arrays to provide a deeper level of data nesting and processing than normal basic arrays.
<body>
<script>
var people = [
[ "Joseph",27,"United States",["blue","black"] ],
[ "Maria",21,"Uraguay",["brown","green"] ],
[ "Brian",35,"United Kingdom",["green","red"] ],
[ "Susan",42,"Australia",["blue","blonde"] ]
];
// people[2][3][1] = "brown";
// document.write(people[2][3][1]);
for(var i = 0; i < people.length; i++) {
document.write("<h2>"+people[0]+"</h2>");
for(var j = 0; j < people.length; j++) {
document.write(people[j]+"<br>");
}
}
