Following are the description of the given question
This is JavaScript code .Here items are the variable that are holding the integer value "3".
After that there is 2 loop are iterating one is outer and one inner loop.
When i=1 1<=3 the condition of outer loop is true the control moves the inner loop .
In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=1 1>=1 condition of inner loop is true it executed the statement inside the inner loop so result =1 .Now we increment the value of i of the outer loop.
i=2 2<=3 the condition of outer loop is true the control moves the inner loop .
In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=2 2>=1 condition of inner loop is true it executed the statement inside the inner loop so result =2 .Now we increment the value of i of the outer loop.
Now i=3 3<=3 the condition of outer loop is true the control moves the inner loop .
In the inner loop there is variable result that is initialized by 1 Now checking the condition of inner loop j=i i.e j=3 3>=1 condition of inner loop is true it executed the statement inside the inner loop so result =6 .Now we increment the value of i of the outer loop.
i=4 4<=3 the condition of outer loop is false the control moves from the outer loop.
the reason HTML seems to work even if it has syntax errors is due to browser having built in ways to parse the code meaning it will still show but most likely look way different then you would want.
