JavaScript is rather tricky as a first language, it owes a lot of it's syntax to C, C# and Java - so that presumes some prior programming chops.

I would suggest learning Python. It has far less syntax and the indentations actually are logical if you think of them as sub-sections to the enclosing section - as in structured writing.

If you do decide to give Python a try, have a look out for tutorials with Turtle Graphics, it's nice to have early feedback. Since you are starting out now, I recommend going straight to Python v3.x - BTW it works equally well on Windows, Mac and Linux - so nothing to fear there.
