Basic Javascript variable use

[iwgalloway]

Hi - I'm VERY new to Javascript and I'm editing a script used in my site...

The script sets a lot of variables as follows

var imagepath="0_galleries/05_12_15/Thumbs/" 
var targetlinkdir="0_galleries/05_12_15/Full/"

etc etc etc

I want to have the

05_12_15

bit of the string defined by another variable, so that I only have to change one variable to update the page.

How would I define this variable and use it within the other variables' paths?

Thanks

[attn]var blah = "05_12_15";[/attn]
var imagepath="0_galleries/[attn]" + blah + "[/attn]/Thumbs/"
var targetlinkdir="0_galleries/[attn]" + blah + "[/attn]/Full/"
