Why doesn't the shorthand escape_javascript actually work?

Question

Here's my biopsis

Works :

:plain
  console.log("#{escape_javascript(render(@job_charge).html_safe)}");

Does not work ( but should? ) :

:plain
  console.log("#{j render(@job_charge).html_safe }");

Answer 1

It looks like j is actually shorthand for json_escape, not escape_javascript.
