Replace ruby string with gsub with conditions for multiple strings

Question

I have as string as "pas" and "with_pas". I want to replace it with blank string. Now I am doing as follows

string.gsub("pas","").gsub("with_pas","")

In some scenario i get the string as "pas" and in some other with "with_pas".

Is there a better way to do this?

You can use your current approach, but will need to change the order, otherwise it won't work as expected:

string.gsub("with_pas","").gsub("pas","")

What about using a regex?

string.gsub(/(with_)?pas/, "")

str.gsub(/pas|with_pas/, '').squeeze

This will remove the words and squeeze will remove the extra space that gsub added.
