1st loop x=x + "The number is " + i + "<br>"; ( "" The number is 0 <br>) 2nd loop x=x + "The number is " + i + "<br>"; ( "" The number is 0 <br>The number is 1 <br>) 3rd loopx=x + "The number is " + i + "<br>"; ( "" The number is 0 <br>The number is 1 <br>The number is 2 <br>) and so on x is overwitten by the x variable current text value it stores, plus the new for loop text and variable value added to the end of it.
