    One I make often is I place a "." instead of a "+" this is because I'm used to coding php more than javascript, Once I make this mistake because of the amount of lines I have coded it takes a while to find my error.

    Most common mistake is not checking for null condition for a variable and using it in your script!

    Well, I find that when I start typing really fast, I make a lot of mistakes. You can avoid this by typing slowly or just keeping your eyes on your screen to see if you mess anything up.

    My common mistake is I misread the instructions of what I am asked to code or I will just type way too fast and then I will suddenly get an error message when I try to use the code and then have to go back and figure out where I went wrong.

    For me I find using Jquery easier than Javascript but with javascript you can run it straight in the users browser with no library. When coding Jquery and Javascript the main proportion of my script would be Javascript and awesome effects in Jquery.

    " ; " are the killers of any programming language.
    My second one is same as @jakemadness stated. Using "." instead of "+" because of PHP love.

    At the moment, I don't code in javascript, so I'm sure I would make many mistakes. Though I like learning new things, even coding. It will be a fun challenge to learn how to code in javascript.
