I am in the process of wrting a script that will open a file and create some text layers to a comp. I am using the script Dan's website motionscript. I have a couple question though:

1. Are all of javascripts functions able to be used in after effects? I am wondering if I can use a text file with a JSON structure and then use JSON.parse() to create a javascript object and go from there?

2. Am I able to create expressions, keyframes for those expressions, add presets and everything else through scripting? Just wondering before I get going on this on to realize its not possible.

Thanks for the help.

The ExtendScript language used by After Effects is an extended form of JavaScript. So, yes, you should be able to use standard JavaScript commands.

Yes, you can do things like set keyframes, operate on expressions, and apply animation presets with scripts.

You can read all about it here and in the resources that that page points to.
