Basically
1024 = 210
(2 * 2 … 10 times)
The for loop loops 10 times, each time result is multiplied by 2 (was 1 initially).
Indenting you code gives
var result = 1;
for ( var counter = 0; counter < 10; counter = counter + 1)
result = result * 2;
console . log ( result ); // display result in console
