For the record, you should just swap using a third string. Other methods are inefficient.
In pseudocode:
// We want to swap these two.
string1
string2
length1 = string1.length
length2 = string2.length
string1 = string1 + string2
string2 = first length1 characters from string1
string1 = last length2 characters from string1

There are two ways in which you can swap without a third variable. 1. Using xor operation swap( int *a, int *b) { *a = *a ^ *b; *b = *a ^ *b; *a = *a ^ *b; } 2. Using addition and subtraction swap( int *a, int *b) { *a = *a + *b; *b = *a - *b; *a = *a - *b; } }

How do you write a javascript to swap two numbers without using third one?
By using the algorithm of bitwise EORing (Exclusive ORing) the numbers together:If the two numbers are X and Y, then to swap them:X = X EOR YY = Y EOR XX =X EOR Ywill swap them.With knowledge of that algorithm, one then uses the syntax of Javascript to implement it.
