PHP's use() syntax is because PHP doesn't have actual lexical

"Injecting variables into a function" is typically done by passing arguments.

This is functionally identical to:
fn = function(value) { return function() { console.log(value); };
fn("hello")
Using the Function constructor here doesn't seem to offer anything at
all over just writing a normal function. Am I missing something?
