eval-js is a simple VS Code plugin that evaluates highlighted code as JavaScript. It's very useful for wrangling large-ish files of text where you need to do a little bit of math or a little bit of string munging. Try it now or check out the code (https://github.com/elliotaplant/eval-js)

Why did you make it?

I loved Atom and it's multi-cursor support. There was a JS Eval extension for Atom (I may have written it?) that let you evaluate highlighted text as JS on multiple cursors. There wasn't a similar plugin for VS Code, so when Atom was sunset, I made this for myself.
