The value of one variable is assigned to an other and vice versa.

//Defining the variables with values
var a=1,b=2;
// swap logic
a = [b][b = a, 0];
// [b] - Puts b in an array
//[b = a,0] - Assign a to b and return 0
// alerting the swapped variables with values
alert("Swapped: a="+a+",b="+b+".");

## Notes :

You can also try this traditional method(oldfolks) but the above one is well reformed.

```
var a = 1;
var b = 2;
a = a + b;
b = a - b;
a = a - b;
alert("Value of a" + a + " and value of b"+b);
```

## Algorithm :

- Assign two variables with values

- Swap the two numbers using the logic,a = [b][b = a, 0];

- Print those swapped variables
