AND in Regex

Raw

and_in_regex.md

Called a look-ahead expression, we can use this to match multiple expressions:

Syntax:

(?=match this expression)(?=match this too)(?=oh, and this)

Example - match string containing the words 'ruby' and 'rails' (regardless of order of occurence):

"ruby rails".match(/(?=.*ruby)(?=.*rails)/)
