Dipping my toes into the Node.js ecosystem
Just to get my feet wet, I published a Node.js module called xirr.
When I was writing the unit tests for the module I had a particular case where the Newton's method implementation was not converging and the library I was using returned false. My son, who has done a bit of coding was shoulder surfing and was asking me what we needed to do to make the the value be true. When I explained that we actually wanted the library to return a number instead his head practically exploded. So I went into the difference between a statically typed and dynamically typed language and he asked "Why don't you just change it to statically typed?"
So, how about EmcsScript committee? Up for making ES7 a statically typed language?
