Hi, i am new to javascript and am finding something which i can't do which is how to increment and decrement properly. I have been trying to do it mostly all day but does not work. Help is much appreciated. And if you have a comment to make, can you please try to explane it so it's not to hard to understand.thanks :)so do they work like this?var string1 = 20;var string2 = string1++;alert(string2);alert(string1);i think i am right but not sure. And is that all their is?

Is that your code exactly? Although you are calling it a string, as long as you don't have quotes around it then yes, that should work. Did you try it? What are you getting instead?

think you looking forvar string1 = 20;string1++;var string2 = string1;alert(string1);alert(string2);orvar string1 = 20;var string2 = ++string1;alert(string1);alert(string2);

Basicly if i load my first comment's piece of code into the browser with the alert changed back to alert(string1); being up the top, you get 21 followed by 20. I just wanted to know why it did the 21 first, and what all the different type of increments and decrements are as the book i have a home explanes it in a really hard to understand way. And thankyou for your help

I think the top one would have been a better way of doing it, because with my one i had the change the alerts the other way around. Thankyou for your time and help
