Hey I have an interesting question, I work with a platform that uses server-side javascript, but unfortunately this platform only supports ECMAscript 3.0. What's the easiest way for me to tell what arrays/methods are available for me to use within thi version?
I know some of the obvious things (i.e. arrow functions and most array methods), but i've definitely spent hours over code, wondering why it wasn't working in this platform, to figure out it's because i'm using an unsupported method.
