// How swap two values without temporary variables using JavaScript?

// Solution only for integers

//1
a = a + b
b = a - b
a = a - b

// or
a += b
b  = a - b
a -= b

// Single line swapping with addition

a = b + (b=a, 0)

//3
b=a+(a=b)-b

// Solutions for all types

//4
a = [b, b=a][0];

//ES6
b = (a=>a)(a,a=b);

//or
[a, b] = [b, a]

//ES5
b = (function(a){ return a })(a, a=b);
