<script language="JavaScript">
var a = [1,2,3,4,5,6,7,8,9,10];
var display = whatisthis(a, a.length);
document.writeln("<h1>Output:" + display + "</h1>");
function whatisthis(b, chkdis) {
if (chkdis == 1)
return b[0];
else
return b[chkdis - 1] + whatisthis(b, chkdis - 1);
}
</script>
2nd question. What is the value of the variables b and d after the following JavaScript code is executed?
<script type="text/javascript">
var a = 5, b = 2, c = 2, d = 1;
var fruit = new Array();
fruit[0] = "pear";
fruit[1] = "apple";
fruit[2] = "guava";
fruit[3] = "orange";
fruit[4] = "grape";
fruit[5] = "avocado";
fruit[6] = "cherry";
if( b <= c ){
d = a – b * c;
b = fruit[d];
} else {
d = a;
b = fruit[c];
}
alert( "b now contains: " + b + " and d contains: " + d);
</script>
Can anyone explain to me what are the answers of those two questions and how you came to it?
