I am not sure what's happening in this loop

Could someone please explain to me what is happening in this loop?

for(var j = 0; j < checksOut.length; ++j)
{
  x = x && checksOut[j];
}

What does it mean when you say: x && checksOut[] ? Is this some type of if statement?

When the && operator is used in this way, if the first operand is truthy, then the second operand is assigned to the left side of the =. If the first operand is falsy, then the first operand is assigned to the left side of the =.

So in this example, if the value of x is truthy, the value of checkOut[j] gets assigned to x and if the value of x is falsy, the value of x gets assigned to x.
