Answer 1

@handerson scott:

You luckily right, as the OP ask for JS, not for C++ ;)

... in JS:

var s1 = "A test sentence";
var s2 = "A test sentence";

if (s1==s2)
alert("equals!");
else
alert("not equals!");

Answer 2

give any example what you want to say

Answer 3

Yes it can be used to compare two string , for example :

Comparing two string using strcmp :

if ( strcmp ( s1, s2 ))

The strcmp function compare two array s1 , s2 containing the string and return 0 if they are equal or return a nonzero value if not equal.

For example :

char s1 [80] = "String" ;
char s2 [80] = "String" ;

if ( !strcmp ( s1 , s2 ))
cout << "They are equal ! " ;
else
cout << "They are not equal " ;

Note : The ! inverts the value .
