using sed to find and replace in bash for loop

Question

I have a large number of words in a text file to replace.

This script is working up until the sed command where I get:

sed: 1: \"*.js\": inval

Answer 1

You're running BSD sed (under OS X), therefore the -i flag requires an argument specifying what you want the suffix to be.

Also, no files match the glob *.js.
