x++, ++x, x--, - - x

Question

What different? Example?? 😉

Answer 1

If you write ++ before the variable, the addition is made before the statement. If you write it after the variable, it is made after the statement. Example:

// both x and y will be 4
var x = 3;
var y = ++x;

// x will be 4, y will be 3
var x = 3;
var y = x++;

Answer 3

++x; // x = x + 1; return x;
x++; // return x; x = x + 1;
