Question

What will be the output of the following Javascript code?

    var string1 = "Letsfindcourse";

    var intvalue = 30;

    alert( string1 + intvalue );

a) Letsfindcourse 30

b) 30

c) Letsfindcourse30

d) Exception

Answer 1

Answer:-  C

Reason:In JavaScript the alert function does the type casting and converts the integer value to string. After that it concatenates both the strings and shows the result as a concatenated string. Thus Letsfindcourse30 would be correct.
