How the code work ( JavaScript code explain)

Question

Please explain the code in detail. Here is the code:

var x = 0;
while(x<6) {
x++;
}
document.write(x);

Answer 1

In this code it starts by declaring a variable (x) set to 0.

#var x = 0;

Then a starting point for a while loop is added with a condition for the loop (x<6).
Which means that the loop will run until the variable (x) is less than 6.

#while(x<6) {

Inside the loop the value of the variable (x) is incremented in order to avoid an infinite loop(so that eventually the condition will become false).

#x++;
#}

After the loop finishes interating.

#document.write(x);

The final statement displays the value of the variable (x).
