With mathematical operations
a = a + b
b = a - b
a = a - b
XOR
For instance, you can use the bitwise XOR operator:
a = a ^ b
b = a ^ b
a = a ^ b
Single line swapping with addition
a = b + (b=a, 0)
1. (b=a, 0) sets b to the old value of a and yields 0
2. a = b + 0 sets a to the old value of b
Since ES6, you can also swap variables more elegantly.
You can use destructuring assignment array matching:
[a, b] = [b, a]
a=(a*b)/(b=a);
