How to find a string, within a string, using Regex

Do you have them in an array? That'd be ideal, as you could do something like this:

const getWords = arr => {
   const regEx = /macports?/i
   return arr.filter(x => regEx.test(x))
}

If no array, then forget about the filter, but you can still apply the same principle.

Another way to go would be:

string.includes("macport")

Though you might have to turn the string into lower case for this one.

/macport$|macport /g.test(string)

This will check for words having macport and a space appeneded or a string that ends with macport

for macports you can do the same thing by replacing macport with macports

I am on mobile so didn't check it much just check if it is working and I may have missed some cases

in ruby if checking per string

 "The fastest macport".include?('macport')
