Refactoring with regular expressions

I’m re-learning JavaScript, and I noticed I was refactoring functions a lot on some old code. I’m putting some useful stuff here for reference:

aFunc(blah) → this.aFunc = function(blah)

Find: function (\w+)\(

Replace with: this.\1 = function\(

 

To go the other way:

Find: \t(\w+)\s=\sfunction\(

Replace with: \tfunction \1\(

 

Change aFunc(blah) to SOME.qualifier.aFunc(blah)

Find: \t(\w+\()

Replace with: \tSOME.qualifier.\1
